Calculate the entropy changes for the following reactions :
(i) `2CO(g) + O_(2)(g) to 2CO_(2)(g)`
(ii)`2H_(2)(g) + O_(2)(g) to 2H_(2)O(l)`
Entropies of different compounds are :
`CO(g) = 197.6 J K^(-1) "mol"^(-1), O_(2)(g) = 205.03 J K^(-1) "mol"^(-1)`
`CO_(2)(g) = 213.6 JK^(-1) "mol"^(-1), H_(2)(g) = 130.6 J K^(-1) "mol"^(-1)`
`H__(2)O(l) = 69.96 J K^(-1) "mol"^(-1)`
