Question 56

Steam methane reforming is widely used to produce hydrogen gas for fuel cells.

CH4(g)+H2O(g)→CO(g)+3H2(g) \text{CH}_4\text{(g)} + \text{H}_2\text{O(g)} \rightarrow \text{CO(g)} + 3\text{H}_2\text{(g)} CH4​(g)+H2​O(g)→CO(g)+3H2​(g)

Explain how the atom economy of this process can be improved.
