Below are sample questions representative of the exercises included on this worksheet and related 11.84 Thermodynamic Favorability and Temperature skill assessments:

Problem 1Difficulty: Mastery

A table shows that heating changes K from 6.0 to 1.5 for A ⇌ B. Which claim best explains the forward reaction?

AThe forward reaction is endothermic because products become less favored at higher temperature.

BThe forward reaction is neither endothermic nor exothermic because K stays positive.

CThe forward reaction has no entropy change because K changes with temperature.

DThe forward reaction is exothermic because products become less favored at higher temperature.

Solution & Explanation:K decreases when temperature increases, so adding heat makes products less favored. Heat behaves like a product, which means the forward reaction is exothermic.

Problem 2Difficulty: Mastery

A reaction has ΔH = +84 kJ/mol and ΔS = +0.140 kJ/(mol·K). Which statement best describes its temperature dependence?

AIt is product-favored only below 600 K.

BIt is product-favored at all positive temperatures.

CIt is product-favored only above 600 K.

DIt is never product-favored at positive temperatures.

Solution & Explanation:The crossover temperature is T = ΔH/ΔS = 84/0.140 = 600 K. With ΔH > 0 and ΔS > 0, only temperatures above the crossover make ΔG negative.

Problem 3Difficulty: Mastery

A reaction has ΔH = -45 kJ/mol and ΔS = -0.120 kJ/(mol·K). Which temperature range is product-favored?

AT > 375 K

BT < 375 K

COnly T = 375 K

DNo positive temperature range

Solution & Explanation:The crossover is T = (-45)/(-0.120) = 375 K. For ΔH < 0 and ΔS < 0, product favorability occurs below the crossover temperature.
