Current Question (ID: 18327)

Question:

$\text{The relationship between temperature and the variance in reaction rate is:}$

Options:

1. $\text{Graph 1: Linear increase of rate with temperature}$
2. $\text{Graph 2: Exponential increase of rate with temperature}$
3. $\text{Graph 3: Linear decrease of rate with temperature}$
4. $\text{Graph 4: Exponential decrease of rate with temperature}$

Solution:

$\text{Use Arrhenius equation.}$ $\text{Explanation: } k = A \times e^{-E_a/RT}$ $\text{As temperature increases, } \frac{E_a}{RT} \text{ will decrease and } e^{-E_a/RT} \text{ will increase.}$ $\text{So } k \text{ will increase exponentially.}$ $\text{Thus, the rate increases with temperature but not directly.}$
