View SolutionGiven below are two reactions involved in the commercial production of dihydrogen $(H_2)$. The two reactions are carried out at temperatures $T_1$ and $T_2$ respectively:
$C_{(s)} + H_2O_{(g)} \xrightarrow{T_1} CO_{(g)} + H_{2(g)}$
$CO_{(g)} + H_2O_{(g)} \xrightarrow{T_2} CO_{2(g)} + H_{2(g)}$
The temperatures $T_1$ and $T_2$ are correctly related as:
$C_{(s)} + H_2O_{(g)} \xrightarrow{T_1} CO_{(g)} + H_{2(g)}$
$CO_{(g)} + H_2O_{(g)} \xrightarrow{T_2} CO_{2(g)} + H_{2(g)}$
The temperatures $T_1$ and $T_2$ are correctly related as:
