7. Energy, Rate and Equilibrium

Select correct answer(s) that would yield more products in the following reaction.

CH₄(g) + 4 F₂(g) ⇌ CF₄(g) + 4 HF(g) ΔH = 38.2 kJ/mol

a) increase pressure

b) increase temperature

c) add 0.31 moles of F₂

d) add some Xenon gas

e) cool down reaction vessel

f) decrease volume

At 26°C Kp = 2.3 x 10^–12 and at 56°C Kp = 3.7 x 10^–5 for the hypothetical reaction. Determine if the reaction is endothermic or exothermic.

AB(s) + 2 B(g) ⇌ 3 BB (g) + C (g)
