NTA JEE Main 10th April 2023 Shift 1 - Question 36
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
$$C(s) + H_2O(g) \xrightarrow{T_1} CO(g) + H_2(g)$$
$$CO(g) + H_2O(g) \xrightarrow{T_2, Catalyst} CO_2(g) + H_2(g)$$
The temperatures T$$_1$$ and T$$_2$$ are correctly related as
