Consider the simple isomerization

\mathrm{A} \rightleftharpoons \mathrm{B}

with

\Delta G^\circ = -3.55\,\text{kJ mol}^{-1}

at 298 K. A sealed flask initially contains exactly 1.0 mol of

\mathrm{A}

and no

\mathrm{B}

. Assuming the total amount of substance remains approximately 1.0 mol, calculate the percentage of

\mathrm{B}

present when equilibrium is reached at 298 K.
