Question

For the equations
$C (diamond) +2H_2(g )\to CH_4(g); \Delta H_1,$
$C(g) + 4H (g )\to CH_4(g);\Delta H_2$
Predict whether

• A. $\Delta H_1 = \Delta H_2$
• B. $\Delta H_1 > \Delta H_2$
• C. $\Delta H_1 < \Delta H_2$
• D. $\Delta H_{1}=\Delta H_{2}+\Delta_{\text{vap}}H\left(C\right)+\Delta_{\text{diss}}H\left(H_{2}\right)$

Answer 1

Answer: (B)

$\Delta H_1 > \Delta H_2$. As diamond has got more strength of bonding in it.
