[单选题]
Which of the following reactions has the largest rate constant, $\kappa$, under the same reaction conditions?
$\kappa$=Ae$^{-Ea/RT}$
A. 30.0 $2\times 10^{12}$
B. 15.0 $2\times 10^{12}$
C. 30.0 $1\times 10^{12}$
D. 15.0 $1\times 10^{12}$
参考答案:
B
本题详细解析:
B
The rate constant increases with increasing A and decreases with increasing $E_a$.
This question is on the lower end of the medium-difficulty category as students should be familiar with the effect of these variables on $\kappa$, and are given the equation for assistance if needed.
