Consider the following reaction at 298K

Consider the following reaction at 298KNH41 CN1- HCN NH3.Determine G^o Q and G at 298K for the following concentrations if K = 1.70[NH3] [NH41 ] [CN1-] [HCN]0.200 M 0.160 M 0.130 M 0.180 Ma. G^o = -1.315 kJ/mol.b. Q = 1.73c. G = ? kJ/mol.I got the first two right but for some reason keep getting C wrong. I kept getting .043 kj/mol and even tried -.043 and both were incorrect. Thanks for any help.
