Question

Using the data provided, calculate the multiple bond energy (kJ mol⁻¹) of a $C \equiv C$ bond in C₂H₂. That energy is (take the bond energy of a C – H bond as 350 kJ mol⁻¹)
$2C(s) + H_2 (g) \longrightarrow HC \equiv CH(g)$; $\Delta H$ = 225 kJ mol⁻¹
$2C(s) \longrightarrow 2C(g)$ ; $\Delta H$ = 1410 kJ mol⁻¹
$H_2 (g) \longrightarrow 2H(g)$ ; $\Delta H$ = 330 kJ mol⁻¹
(a) 1165
(b) 837
(c) 865
(d) 815
