Below are sample questions representative of the exercises included on this worksheet and related 11.92 Arrhenius Equation and Temperature Effects skill assessments:

Problem 1Difficulty: Mastery

Two reactions have the same k at 300 K, but Reaction L has Ea = 30 kJ/mol and Reaction M has Ea = 80 kJ/mol. If both are warmed to 320 K and their Arrhenius behavior stays constant, which reaction should have the larger k at 320 K?

AReaction L

BThey must still have exactly the same k.

CNeither, because warming makes k smaller.

DReaction M

Solution & Explanation:Starting from the same k, the reaction with the larger Ea changes by a larger factor when temperature rises, so Reaction M becomes larger at 320 K.

Problem 2Difficulty: Mastery

A student says, 'A larger activation energy means a faster reaction.' Which correction is most accurate for reactions with similar A at the same temperature?

AA larger activation energy always means a larger k.

BActivation energy has no connection to rate constants.

CA larger activation energy usually means a smaller k, but greater temperature sensitivity.

DA larger activation energy makes temperature irrelevant.

Solution & Explanation:At the same T and similar A, larger Ea makes the exponent more negative and k smaller, while also making k more sensitive to temperature changes.

Problem 3Difficulty: Mastery

A reaction has k = 0.15 s^-1 at 330 K and Ea = 70 kJ/mol. What is the approximate k at 305 K?

A1.2 s^-1

B0.019 s^-1

C0.15 s^-1

D0.0019 s^-1

Solution & Explanation:Cooling from 330 K to 305 K gives k305/k330 about 0.124. Thus k305 is about 0.15 x 0.124 = 0.019 s^-1.
