A) \[{{H}_{2}}O(g)\xrightarrow{{}}{{H}_{2}}O(l)\]
B) \[{{H}_{2}}+{{I}_{2}}\xrightarrow{{}}2HI\]
C) \[CaC{{O}_{3}}(s)\xrightarrow{{}}CaO(s)+C{{O}_{2}}(g)\]
D) \[{{N}_{2}}(g)+3{{H}_{2}}(g)\xrightarrow{{}}2N{{H}_{3}}(g)\]
Correct Answer: C
Solution :
\[\Delta S\] (entropy change) is the measure of randomness and thus in solid, liquid and gas, the order of entropy is gas > liquid > solid Thus, \[\Delta S\] is positive for the reaction given in option [c].You need to login to perform this action.
