Consider the decomposition of liquid benzene, C6H6(l), to gaseous acetylene, C2H2(g):
C6H6(l) Δ 3 C2H2(g) ΔH = +630 kJ
(a) What is the enthalpy change for the reverse reaction? (b) What is ΔH for the formation of 1 mol of acetylene? (c) Which is more likely to be thermodynamically favored, the forward reaction or the reverse reaction? (d) If C6H6(g) were consumed instead of C6H6(l), would you expect the magnitude of ΔH to increase, decrease, or stay the same? Explain.
