Given below are two reactions, involved in the commercial production of dihydrogen (H 2 ). The two reactions are carried out at temperature "T 1 " and "T 2 ", respectively C(s) + H 2 O (g)   1 T CO (g) + H 2 (g) CO (g) + H 2 O (g) Catalyst T 2 CO 2 (g) + H 2 (g) The temperatures T 1 and T 2 are correctly related as

1. T 1 = T 2
2. T 1 < T 2
3. T 1 = 100 K, T 2 = 1270 K
4. T 1 > T 2

Correct answer: T 1 > T 2
