This document provides information to construct a potential energy diagram for a two-step reaction, including the potential energies of the reactants (400 kJ) and intermediates (250 kJ), activation energies for each step (step 1: 200 kJ, step 2: 300 kJ), and the heat of reaction (-100 kJ). Using this data, one can draw and label a potential energy diagram and calculate the overall heat of reaction for the multi-step process.

Construct and label a potential energy diagram for the two step reaction,
using the information below. Calculate the heat of reaction for the
overall reaction.
PE of reactants = 400kJ
PE of intermediates = 250 kJ
Ea for step 1 = 200kJ
Ea for step 2 = 300 kJ
H = -100 kJ
