Assignment:
Q1. Sketch a diagram representing an exothermic reaction. Label both the horizontal and vertical axes. Show reactants and products, energy of activation and (delta Hrxn) on your sketch.
Q2. Find (delta Hrxn) for the reaction CO(g) + NO2(g) --> CO2(g) + NO(g). Is the reaction exothermic or endothermic? Explain.
Provide complete and step by step solution for the question and show calculations and use formulas.
