Equilibrium
How might altering one's diet so meals contain predominantly proteins instead carbohydrates affect urinary pH over time assuming all else remains constant including respiratory function & fluid intake levels?
No significant changes as the overall balance between the intake and output of various acidic and basic substances remains unchanged regardless of macronutrient composition.
A slightly acidic urine due to the acidic nature of amino acids released during protein metabolism, versus the alkaline effects often associated with carbohydrate breakdown.
A slightly basic urine given the larger quantities of hydrogen ions consumed via increased carbohydrate ingestion, leading to excess acid neutralization.
Highly acidic urine due to the rapid accumulation of organic acids as the body struggles to maintain homeostasis with a high load of protein introduction into metabolic pathways.
When considering Le Chatelier’s principle, how might increasing pressure influence a reversible reaction with unequal moles of gaseous reactants and products?
Lowering volume tends increase collisions pushing equilibrium towards side with more gas moles produced regardless molar ratio present sides involved
Increasing pressure typically shifts the equilibrium towards fewer moles of gas being produced whether those are on side with reactants or products depends on stoichiometry
No matter what changes done atmospheric conditions end result remains same because intrinsic properties compounds dictate final outcome above external interventions applied
Applying additional external force under high pressures causes direct conversion all substances into liquid phase thereby eliminating any relevance regarding mole amounts per state present
What will be an immediate consequence for an endothermic reaction at equilibrium if its surroundings' temperature suddenly increases?
Shifts in favor of products forming because heat acts as a reactant.
No shift occurs as temperature affects only rate but not position of equilibrium.
Shifts in favor of reactants due to decreased kinetic energy in system.
Shifts temporarily toward products then back to original balance as new dynamic equality establishes itself quickly after perturbance.
How would decreasing pressure by increasing volume in a gaseous equilibria involving unequal moles per side influence its position?
No effect because total number of particles remains unchanged.
Favors side with fewer moles due to lowered partial pressures.
Causes both forward and reverse reactions to speed up equally without shifting balance.
Favors side with more moles of gas due to increased entropy.
In a chemical equation, what does the coefficient in front of a compound or element represent?
The concentration of that substance in solution.
The physical state of that substance.
The number of moles of that substance.
The temperature at which the reaction occurs.
What is the primary intermolecular force present in a sample of liquid bromine (Br2)?
Ionic bonding
London dispersion forces
Dipole-dipole interactions
Hydrogen bonding
When does increasing temperature generally favor the endothermic direction of a reversible reaction?
When the exothermic reaction produces excess heat.
Neither reactants nor products are affected by the temperature change.
When increasing temperature creates a greater barrier for the endothermic direction only.
When the endothermic direction absorbs heat.

Which change would increase the amount of product formed in an endothermic reversible reaction at equilibrium?
Adding an inert gas to the mixture without changing pressure or volume.
Increasing the total pressure in the system (if gases are involved).
Lowering the total pressure in the system (if gases are involved).
Removing one of the products from the mixture as it is formed.
Consider the reaction 2H2(g) + S2(g) ⇌ 2H2S(g). If the concentration of H2S is increased, what is the effect on the direction of the reaction at equilibrium?
The reaction will shift to the right.
There will be no effect on the direction of the reaction.
The reaction will shift to the left.
It is impossible to determine the effect on the direction of the reaction.
How does adding a catalyst affect a reversible reaction at chemical equilibrium?
It slows down both forward and reverse reactions equally but doesn't affect equilibrium position.
A catalyst has no effect on either rate or direction of reversible reactions at chemical equilibrium.
It accelerates both forward and reverse reactions equally without shifting equilibrium position.
It shifts the equilibrium toward more products being formed.
