Reduction half reaction.
Cr? O? ²? + 14H? + 6e? → 2Cr? ³ + 7H? O
Oxidation half reaction
SO? ²? + H? O → SO? ²? + 2e? ] * 3
Oxygen is balanced by adding water and hydrogen is balanced by adding H? and the charge is balanced by electrons.
Add ( eq. (i) + (3 * eq. (ii) )
Cr? O? ²? + 3SO? ²? + 8H? → 2Cr? ³ + 3SO? ²? + 4H? O
a = 1 b = 3 c = 8

Keq. = ( [C] [D])/ ( [A] [B])
Keq = (10 * 6)/ (2 * 3) = 10
ΔG° = −2.303RTlog Keq. = −2.303 (2) (300) (log 10)
= −1381.8cal (? R = 2cal/molk)
