Consider a biochemical reaction under standard conditions. The change in enthalpy is -7 kJ/mol and the change in entropy is -25 JK^-1 mol^-1. Without doing any calculations, can you determine if the reaction is spontaneous? Calculate delta G^degree' for the reaction at 5 degree C. Is the reaction spontaneous or not? Why or why not? If not, does raising the temperature make the reaction more likely to be spontaneous, or less likely to be spontaneous?
