A reaction A ( aq ) + B ( aq ) − ⇀ ↽ − C ( aq ) has a standard free‑energy change of − 5.24 kJ / mol at 25 °C. What are the concentrations of A , B , and C at equilibrium if, at the beginning of the reaction, their concentrations are 0.30 M, 0.40 M, and 0 M, respectively?

Explanation:

Hello,

In this case, for the given reaction, based on the information about its Gibbs free energy, we obtain the equilibrium constant as shown below:

Now, by means of the law of mass action in terms of the undergoing change due to the chemical reaction, we obtain:

For which the solution for by solver is:

Thus, the equilibrium concentrations result:

Best regards.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

if you're asking what comes out, it's steam.
