Questions & Step-by-Step Solutions
What is the relationship between the rate constant k and temperature T according to the Arrhenius equation?
Step 1: Understand that the Arrhenius equation relates the rate constant (k) to temperature (T).
Step 2: The Arrhenius equation is written as k = A * e^(-Ea/(RT)), where 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 temperature (T) increases, the value of -Ea/(RT) becomes less negative.
Step 4: Since the exponential function e^x increases as x increases, a less negative value means that e^(-Ea/(RT)) increases.
Step 5: Therefore, as temperature increases, the rate constant (k) also increases.
