Several gas-phase reactions at 298 K are plotted on a coordinate system where the standard free energy change,

\Delta G^{\circ}

, is on the y-axis and

\ln K

is on the x-axis. Which of the following correctly describes where the data point for a reaction with

K>1

would appear? (a) Positive

\ln K

and positive

\Delta G^{\circ}

(b) Negative

\ln K

and negative

\Delta G^{\circ}

\ln K

and negative

\Delta G^{\circ}

(d) Positive

\ln K

and

\Delta G^{\circ}

close to zero
