Question: What is the relationship between the rate constant and temperature according to the Arrhenius equation?

Options:

  1. Rate constant is independent of temperature
  2. Rate constant increases with temperature
  3. Rate constant decreases with temperature
  4. Rate constant is constant at all temperatures

Correct Answer: Rate constant increases with temperature

Solution: 

According to the Arrhenius equation, the rate constant increases with temperature due to the exponential dependence on the negative activation energy divided by temperature.

Questions & Step-by-Step Solutions

What is the relationship between the rate constant and temperature according to the Arrhenius equation?
  • Step 1: Understand that the rate constant is a number that helps us know how fast a reaction happens.
  • Step 2: Learn about the Arrhenius equation, which is a formula that shows how the rate constant changes with temperature.
  • Step 3: The Arrhenius equation includes the activation energy, which is the energy needed for a reaction to occur.
  • Step 4: Notice that the equation has a negative sign in front of the activation energy divided by temperature.
  • Step 5: Realize that as temperature increases, the value of temperature in the denominator gets larger, making the whole fraction smaller.
  • Step 6: Since the fraction is negative, a smaller value means that the exponential part of the equation increases.
  • Step 7: Conclude that as temperature goes up, the rate constant also increases, meaning reactions happen faster.
