Question

1) The sign of ?G for a reaction is ______ if the reaction is spontaneous, ________ if the reaction is at equilibrium, and ________ if the reaction is nonspontaneous.

2) For the reaction, NH3(g) ? N(g) + 3 H(g), one would expect

3)

The SO3 molecule can be described as having 3 S-O ? bonds and ? molecular orbitals containing

The SO3 molecule can be described as having 3 S-O ? bonds and ? molecular orbitals containing

A. ?H? to be positive and ?S? to be negative. B. ?H? to be positive and ?S? to be positive. C. ?H? to be negative and ?S? to be positive. D. ?H? to be negative and ?S? to be negative.

Explanation / Answer

1.gibbs energy is a concept used to predict wheter the reaction is spontaneous or not.

Gibbs energy is negative for a spontaneous reaction.zerp in equilibrium and positive if spontaneous.

2.the given reaction is endothermic and so delta h is positive.and entropy is increased so,delta s is positive.

3.the molecular orbits contain 6 electrons and the sulphur atom has one lone pair of electrons on it.
