Which condition describes a spontaneous reaction in terms of energy and entropy? Higher energy; increased entropy Higher energy; decreased entropy Lower energy; increased entropy Lower energy; decreased entropy

Lower energy; increased entropy

What happens to the direction of a reaction when the pressure increases or volume decreases? Shift in direction of more (g) molecules Shift in direction of equal (g) molecules Shift in direction of fewer (g) molecules No shift in direction

Shift in direction of fewer (g) molecules

How does the sign of ΔH (enthalpy change) determine the shift in reaction based on temperature change? Shift always towards products Shift always towards reactants R or P based on sign of ΔH (endo, or exothermic) No shift regardless of ΔH

R or P based on sign of ΔH (endo, or exothermic)

Which statement correctly describes one of the three laws of thermodynamics? Entropy decreases as temperature increases. Heat is a form of energy that cannot be created or destroyed, only converted. Energy can be created or destroyed. The amount of disorder in a system can decrease.

Heat is a form of energy that cannot be created or destroyed, only converted.

When dissolving a solid, what is considered the system and what are the surroundings? Solid is system, H2O is surroundings H2O is system, solid is surroundings Both are systems Both are surroundings

Solid is system, H2O is surroundings

What happens to the entropy of the surroundings and the system during an exothermic reaction? Decrease in S surrounding; increase in S system Increase in S surrounding; increase in S system No change in S surrounding; decrease in S system Increase in S surrounding; decrease in S system

Increase in S surrounding; decrease in S system

During an endothermic reaction, how do the entropies of the system and surroundings change? Increase in S surrounding; decrease in S system No change in S surrounding; increase in S system Decrease in S surrounding; decrease in S system Decrease in S surrounding; increase in S system

Decrease in S surrounding; increase in S system
