# Gibbs free energy

Chemistry Level 2

Assume that, at a constant temperature of $$25 ^\circ \text{C}$$, gas $$\ce{A}$$ was injected into a container and gas $$\ce{B}$$ was produced from gas $$\ce{A}$$. At $$t$$ seconds later, a chemical equilibrium was reached as follows: $\ce{A}(g) \rightleftharpoons \ce{B}(g).$
