If $\Delta G$ for a reaction is negative, then which of the following is true? a. The reaction is spontaneous in the forward direction as written. b. The reaction system is at equilibrium. c. The reverse of the given reaction is spontancous. d. No reaction would ever have a negative $\Delta G$.
Identify the correct statement for change of Gibb's energy for a system $\left(\Delta \mathrm{G}_{\text {system }}\right)$ at constant temperature and pressure: a. if $\Delta \mathrm{G}_{\text {system }}=0$, the system is still moving in a particular direction b. if $\Delta \mathrm{G}_{\text {system }}=-\mathrm{ve}$, the process is not spontaneous c. if $\Delta \mathrm{G}_{\text {system }}=+\mathrm{ve}$, the process is spontaneous d. if $\Delta G_{s y s c m}=0$, the system has attained equilibrium
