Choose the correct expression for Keq and description (homogeneous or heterogeneous) for the following reaction:
Sn2+(aq) + H2(g)---> Sn(s) + 2 H+(aq)
a) Keq = [H+]2 / [Sn2+] PH2; This reaction is heterogeneous.
b) Keq = [H+]2 / [Sn2+] PH2; This reaction is homogeneous.
c) Keq = [Sn2+] PH2 / [Sn] [H+]2; This reaction is heterogeneous.
d) Keq = [Sn2+] PH2 / [H+]2; This reaction is homogeneous.
e) Keq = [Sn2+] PH2 / [H+]2; This reaction is heterogeneous.
