Intermolecular Forces and Properties

CH4(g), because it has more electrons creating stronger collisions with the walls.

Neither, since different gases have unique intrinsic pressures regardless of conditions.

Ar(g), because it is heavier thus exerts more force upon collision with container walls.

Both exert equal pressures due to Avogadro's law.

Both rates initially increase but eventually favors the side with fewer moles of gas.

Only the rate of the forward reaction increases while that of the reverse decreases.

Both rates decrease and eventually favor the side with more moles of gas.

There is no change in either rate; volume changes do not affect gaseous equilibria.

Manganese (Mn)

Scandium (Sc)

Nickel (Ni)

Zinc (Zn)

Vapor pressure increases with temperature, causing tires to need less air on warm days.

Vapor pressure has no temperature dependence; thus, tire pressures remain constant regardless of temperature changes.

Tires may appear under-inflated on cold days due to decreased vapor pressure within them.

Cold temperatures increase vapor pressure, leading tires to expand and appear over-inflated.

liquid and solid forces

covalent and ionic forces

intermolecular and intramolecular forces

cohesive and adhesive forces

Kc decreases since increasing the amount of A leads to more collisions and faster reverse reaction rates.

Kc increases because increasing concentration of A drives the reaction towards products.

Kc remains unchanged since it is only affected by temperature changes.

Kc changes spontaneously based on concentration variations without any thermal influence.
