Question

Given below are two reactions, involved in the commercial production of dihydrogen (H2). The two reactions are carried out at temperature “T1” and “T2”, respectively C(s) + H2O(g) 1 T CO(g) + H2(g) CO(g) + H2O(g) Catalyst T 2 CO2(g) + H2(g) The temperatures T1 and T2 are correctly related as

(A) T1 = T2
(B) T1 < T2
(C) T1 T2
(D) T1 = 100K , T2 = 1270K
