QUESTION ONE

a) State the Arrhenius equation and describe its application in chemical kinetics. (4 marks)

The Arrhenius equation is:

$$k = A e^{-E_a / RT}$$

Where:

• $k$ is the rate constant of the reaction.
• $A$ is the pre-exponential factor or frequency factor, representing the frequency of collisions with correct orientation.
• $E_a$ is the activation energy, the minimum energy required for a reaction to occur.
• $R$ is the ideal gas constant ($8.314 \text{ J mol}^{-1} \text{ K}^{-1}$).
• $T$ is the absolute temperature in Kelvin.
