Question

4. Consider the potential energy diagram for the reaction: AB+C longrightarrow A+BC. a.) Potential energy of the reactants: b.) Potential energy of A + BC : .) Activation Energy : d .) ΔΗ : e.) Is the reaction exothermic or endothermic? f.) Explain how a catalyst would change this energy diagram . g.) What is the name of what is formed at ABC and why ? h.) The compound AB is a gas and the element is a solid. What effect would grinding C into a fine powder have?

Answer 1

a) 52 KJ

b) 18 KJ

c) 80KJ - 52 KJ = 28 KJ

d) $\Delta H$ = -34 KJ

e) exothermic

f) change in activation energy

g) ABC is an intermediate

h) gas may be exposed to more quantity of solid
