A) \[C\,(\text{graphite})+\frac{1}{2}{{O}_{2}}(g)\xrightarrow[{}]{{}}CO(g)\]
B) \[CO(g)+\frac{1}{2}{{O}_{2}}(g)\xrightarrow[{}]{{}}C{{O}_{2}}(g)\]
C) \[Mg(s)+\frac{1}{2}{{O}_{2}}(g)\xrightarrow[{}]{{}}MgO(s)\]
D) \[\frac{1}{2}C(\text{graphite})+\frac{1}{2}{{O}_{2}}(g)\xrightarrow[{}]{{}}\frac{1}{2}C{{O}_{2}}(g)\]
Correct Answer: A
Solution :
Among the given reactions only in the case of C (graphite)![]() ![]() |
Moreover, it is a combustion reaction and all the combustion reactions are generally exothermic, i.e.,![]() |
We know that |
![]() |
![]() |
Thus, as the temperature increases, the value of ![]() |
