You remember that ΔGᵒ is related to RTln(K) but cannot remember if it's RTln(K) or −RTln(K). Realizing what ΔGᵒ K mean, how can you figure out the correct sign?
a. K is always negative
b. ΔGᵒis always positive
c. Determine the sign based on the reaction quotient
d. Use the absolute value of K for the correct sign
