Question: What is the effect of temperature on the rate constant of a reaction according to the Arrhenius equation?

Options:

Correct Answer: Rate constant increases with temperature

Solution:

According to the Arrhenius equation, an increase in temperature generally leads to an increase in the rate constant, k.

What is the effect of temperature on the rate constant of a reaction according to the Arrhenius equation?

Step 1: Understand the Arrhenius equation, which is k = A * e^(-Ea/(RT)).
Step 2: Identify the variables in the equation: k is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the gas constant, and T is the temperature in Kelvin.
Step 3: Note that as temperature (T) increases, the value of -Ea/(RT) becomes less negative.
Step 4: Realize that when -Ea/(RT) is less negative, e^(-Ea/(RT)) increases.
Step 5: Conclude that an increase in e^(-Ea/(RT)) results in a higher rate constant (k).
Step 6: Therefore, according to the Arrhenius equation, an increase in temperature generally leads to an increase in the rate constant, k.
