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

Options:

Correct Answer: Rate increases exponentially with temperature

Solution:

According to the Arrhenius equation, the rate constant increases exponentially with an increase in temperature, leading to a higher reaction rate.

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

Step 1: Understand that the Arrhenius equation relates temperature to the rate of a chemical reaction.
Step 2: The Arrhenius equation is usually written as k = A * e^(-Ea/(RT)), where 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: Notice that as the temperature (T) increases, the value of -Ea/(RT) becomes less negative, which means e^(-Ea/(RT)) increases.
Step 4: Since k (the rate constant) is directly proportional to e^(-Ea/(RT)), an increase in temperature leads to an increase in k.
Step 5: A higher rate constant (k) means that the reaction will occur faster, resulting in a higher reaction rate.
