Based on the standard free energies of formation, which of the following reactions represent a feasible way to synthesize the product? a. 2c(s)+h2(g)→c2h2(g); δg∘f=209.2 kj/molb. n2(g)+3h2(g)→2nh3(g); δg∘f=−33.30 kj/molc. 2c(s)+2h2(g)→c2h4(g); δg∘f=68.20 kj/mold. 2so(g)+o2(g)→2so2(g); δg∘f=−600.4 kj/mol

Option B and D

Explanation:

The Gibb's free energy also referred to as the gibb's function represented with letter G. it is the amount of useful work obtained from a system at constant temperature and pressure. The standard gibb's free energy on the other hand is a state function represented as Delta-G, as it depends on the initial and final states of the system.

A feasible way to synthesize the product entails the spontaneity of the reaction.

The spontaneity of a reaction is explained by the standard gibb's free energy.

If Delta-G = -ve ( the reaction is spontaneous)

if Delta -G = +ve ( the reaction is non-spontaneous)

if Delta-G = 0 ( the reaction is at equilibrium)

Hence the option (B and D) with negative Gibb's free energy are the reaction that are spontaneous.
