Zn(s) + 2H+(aq) Zn2+(aq) + H2(g) has an overall reduction potential of 0.76 V. Therefore,
A. the reaction is not spontaneous and will require energy to proceed.
B. the reaction is spontaneous and will proceed without any energy input.
C. the reduction potentials cancel out and prevent any reaction.
D. the forward and reverse reactions are each spontaneous.
