Homework Answers
Answer A.
Equilibrium constant K is 2.2244 × 10^(-6)
∆G°Ni is taken 0 KJ/mol because Ni(s) present in standard state and gibbs free energy in standard state is 0.
Then we calculate standard free energy of the reaction, ∆G°rxn
R value is taken as 0.008314 KJ/mol.K
Then we calculate equilibrium constant.
Answer B.
We write individual half reaction for each species then balance there charge and atoms then add them so we obtained balance redox reaction.
