Question

2. Below is a Maxwell Boltzmann distribution curve for a sample of gas at a fixed temperature. EAis the activation energy for the decomposition of this gas. No. of molecules with a given energy energy EA (a) Copy this diagram and add the distribution curve for the same sample of gas at a higher temperature. (b) Use the Maxwell-Boltzmann distribution to explain the effect of increasing temperature on the rate of a chemical reaction. (c) What does the area under the curve represent? (d) Use your diagram of the Maxwell-Boltzmann distribution to show and explain the effect of adding a catalyst to the rate of a chemical reaction.
