[单选题]
The rate equation for the thermal decomposition of hydrogen peroxide is $Rate$=$\kappa$$[H_2O-2]$.
Which of the following graphs shows the relationship between the rate and the temperature of this reaction?

A.
B.
C.
D.


参考答案:  C


本题详细解析:
C

The rate constant, $�$, is the feature of the rate equation that is affected by temperature according to the Arrhenius equation$\kappa$=$Ae^{-Ea/RT}.$
The graph of rate vs temperature always shows this general trend, and similar questions have been asked several times in past papers.
The question is of moderate difficulty as the use of a specific example and reference to rate rather than k may derail some students. Confusion with the Arrhenius plot could also lead students to select option B.
