Which of the following reactions is an example of use of water gas in the synthesis of other compounds?Which of the following reactions is an example of use of water gas in the synthesis of other compounds?

Options

  1. ACH4(g)+H2O(g)→Ni1270KCO(g)+H2(g){CH}_{4}\left(g\right) + {H}_{2}O\left(g\right)\mathop{\to}_{Ni}^{1270K}CO\left(g\right) + {H}_{2}\left(g\right)
  2. BCO(g)+H2O(g)→Catalyst673KCO2(g)+H2(g)CO\left(g\right) + {H}_{2}O\left(g\right)\mathop{\to}_{Catalyst}^{673K}{CO}_{2}\left(g\right) + {H}_{2}\left(g\right)
  3. CCnH2n+2+n.H2O(g)→Ni1270Kn.CO+(2n+1)H2{C}_{n}{H}_{2n + 2} + n . {H}_{2}O\left(g\right)\mathop{\to}_{Ni}^{1270K}n . CO + \left(2n + 1\right){H}_{2}
  4. DCO(g)+2H2(g)→CatalystCobaltCH3⋅OH(I)CO\left(g\right) + 2{H}_{2}\left(g\right)\mathop{\to}_{Catalyst}^{Cobalt}{CH}_{3} \cdot OH\left(I\right)

Correct answer

D. CO(g)+2H2(g)→CatalystCobaltCH3⋅OH(I)CO\left(g\right) + 2{H}_{2}\left(g\right)\mathop{\to}_{Catalyst}^{Cobalt}{CH}_{3} \cdot OH\left(I\right)

Step-by-step solution

The mixture of CO(g)CO\left(g\right) and H2(g){H}_{2}\left(g\right) is known water gas as it is used in the synthesis of other compounds.

When carbon monoxide reacts with hydrogen in presence of catalyst cobalt the product formed is methanol. Therefore, water gas is producing a an alcohol in this reaction.

Which of the following reactions is an example of use of water gas in the synthesis of other compounds?
