In the Arrhenius equation k = Ae^(−Ea/RT), what happens to k as temperature rises?

A.k increases
B.k decreases
C.k is unchanged
D.k depends only on A

Explanation

Core Concept

Raising T makes the exponent −Ea/RT less negative, so e^(−Ea/RT) grows and k rises. More collisions exceed Ea at higher temperature.

Correct Answer

Ak increases
