Easy MCQ +4 / -1 PYQ · JEE Mains 2020

The equation that represents the water-gas shift reaction is :

  1. A CO(g) + H<sub>2</sub>O(g) $\mathrel{\mathop{\kern0pt\longrightarrow} \limits_{Catalyst}^{673K}}$ CO<sub>2</sub>(g) + H<sub>2</sub>(g) Correct answer
  2. B CH<sub>4</sub>(g) + H<sub>2</sub>O(g) $\mathrel{\mathop{\kern0pt\longrightarrow} \limits_{Ni}^{1270K}}$ CO(g) + 3H<sub>2</sub>(g)
  3. C C(s) + H<sub>2</sub>O(g) $\buildrel {1270K} \over \longrightarrow$ CO(g) + H<sub>2</sub>(g)
  4. D 2C(s) + O<sub>2</sub>(g) + 4N<sub>2</sub>(g) $\buildrel {1273K} \over \longrightarrow$ 2CO(g) + 4N<sub>2</sub>(g)
