Question

alternate expression of rate constant k2
​

Answer 1

Answer:

would think that the answer would be (C), both temperature and concentration.

Concentration would obviously affect it (from the rate expression), and the temperature would also affect it because the Arrhenius equation for the rate constant is

k=Ae−Ea/(RT)k=Ae−Ea/(RT)

and thus temperature would have an influence on the rate constant, and since the rate constant is part of the rate equation, it would also affect the rate of the reaction itself.

However, the given answer is
