What happens when you increase the partial pressure of a reaction ?

For a reaction $\mathrm{A}\left(\mathrm{g}\right)\rightleftharpoons \mathrm{B}\left(\mathrm{g}\right)$ at equilibrium, the partial pressure of $\mathrm{B}$ is found to be one-fourth of the particle pressure of $\mathrm{A}$. The value of $\mathrm{\Delta G}°$ of the reaction $\mathrm{A}\to \mathrm{B}$ is
