zn(s) + 2h+(aq) mc013-1.jpg zn2+(aq) + h2(g) has an overall reduction potential of 0.76 v. therefore,
the reaction is not spontaneous and will require energy to proceed.
the reaction is spontaneous and will proceed without any energy input.
the reduction potentials cancel out and prevent any reaction.
the forward and reverse reactions are each spontaneous.

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate,m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2
