Identify, giving reasons, the faster reaction in the following:
$C (s) + 2 H_{2} O (g) \to 2 H_{2} (g) + {CO}_{2} (g)$
$C (s) + 2 H_{2} O (s) \overset{Catalyst}{\to} 2 H_{2} (g) + {CO}_{2} (g)$

Solution

C (s) + 2 H_{2} O (s) \overset{Catalyst}{\to} 2 H_{2} (g) + {CO}_{2} (g)

The reaction carried in the presence of catalyst is fast because in the catalysed reaction the activation energy needed is less as compared to the uncatalysed reaction.
