Q. According to Le-Chatelier’s principle, the addition of temperature to the following reaction $CO_{2}(g) + 2H_{2}O(g) \rightarrow CH_{4}(g) + 2O_{2}(g)$ will cause it to the right. This reaction is, therefore

A) Exothermic
B) Unimolecular
C) Endothermic
D) Spontaneous
Explanation

(c)
$CO_{2}(g) + 2H_{2}O(g) \rightarrow CH_{4}(g) + 2O_{2}(g)$
According to Le-Chatelier’s principle, addition of temperature shifts a endothermic reaction towards right. The addition of temperature to the above reaction will cause it to right, hence it is an endothermic reaction. ($\mathrm{\Delta}H = + ve$).
