Question: Which of the following reactions increases production of dihydrogen from synthesis gas?...

Which of the following reactions increases production of dihydrogen from synthesis gas?

A

CH4(g)+H2O(g)→1270KNiCO(g)+H2(g)CH_{4(g)} + H_{2}O_{(g)}\underset{Ni}{\overset{\quad 1270K\quad}{\rightarrow}}CO_{(g)} + H_{2(g)}

B

C(s)+H2O(g)→1270KCO(g)+H2(g)C_{(s)} + H_{2}O_{(g)}\overset{\quad 1270K\quad}{\rightarrow}CO_{(g)} + H_{2(g)}

C

CO(g)+H2O(g)→673KCatalystCO2(g)+H2(g)CO_{(g)} + H_{2}O_{(g)}\underset{Catalyst}{\overset{\quad 673K\quad}{\rightarrow}}CO_{2(g)} + H_{2(g)}

D

C2H6+2H2O→1270KNi2CO+5H2C_{2}H_{6} + 2H_{2}O\underset{Ni}{\overset{\quad 1270K\quad}{\rightarrow}}2CO + 5H_{2}

Answer

CO(g)+H2O(g)→673KCatalystCO2(g)+H2(g)CO_{(g)} + H_{2}O_{(g)}\underset{Catalyst}{\overset{\quad 673K\quad}{\rightarrow}}CO_{2(g)} + H_{2(g)}

Explanation

Solution

: The production of dihydrogen can be increased by reacting carbon monoxide of syngas mixtures with steam in the presence of iron chromate as catalyst.

CO(g)+H2O(g)→673KCatalystCo2(g)+H2(g)CO_{(g)} + H_{2}O_{(g)}\underset{Catalyst}{\overset{\quad 673K\quad}{\rightarrow}}Co_{2(g)} + H_{2(g)}

This is called water-gas shift reaction.
