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.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
