The following reaction has an Eâ—¦ value of -0.76 V?

Question

. Calculate the

∆G◦ and tell whether the reaction is spontaneous as written.

Zn2+(aq) + H2(g) + 2 H2O(l)  Zn(s) + 2 H3O+(aq)

Answer 1

dGo = -nFEo

dGo - nF (-0.76 volts)

dGo = "+"

when ever dG is "+" it is not spontaneous

& that's your answer
