Question
Consider the decomposition of liquid benzene, C6H61l2, to
gaseous acetylene, C2H21g2:
C6H61l2 ¡ 3 C2H21g2 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
the forward reaction or the reverse reaction?
(d) If C6H61g2 were consumed instead of C6H61l2, would you
expect the magnitude of ΔH to increase, decrease, or
stay the same? Explain.
