1.	(a) An endothermicreaction A rarr B proceeds to completion . Predict the sign of DeltaS. (b) What will be the sign of DeltaS for the reaction : N_(2)(g) + O_(2)(g) rarr 2NO(g) ? Given reasons in support of your answer.
Answer» ANSWER :(a)Sinceit is FEASIBLE , so `DeltaG` is-ve. As it is ENDOTHERMIC `DeltaH ` is `+ve`.Hence for `DeltaG`to be `-ve, DeltaS` must be`+ve` . (B) `DeltaS`is `-ve` because there are two different REACTANT while there is only one product.
