Question

(a). An endothermic reaction A--B proceeds to completion. Predict the signs of deltaS.

(b). What will be the sign of deltaS for the reaction : N2(g)+O2(g)--2 NO(g)

Answer 1

▼,▲ these will the sign of delta.

Answer 2

Answer:

a)+ve b)-ve

Explanation:

(a)Since it is feasible , so ΔG is-ve.

As it is endothermic ΔH is +ve

.Hence for ΔG to be −ve, ΔS must be+ve

. (b) ΔS is −ve

because there are two different reactant while there is only one product.
