Homework Answers
Cl2 + F2 < -- > 2ClF delta G1 = 115.4 KJ/mol (1)
Cl2 + Br2 < -- > 2ClBr delta G2 = -2.0 KJ/mol (2)
required equation is
2ClF + Br2 < -- > 2ClBr + F2
this reaction will get when we subtract (1) from (2)
so, delta G of required reaction = delta G2 - delta G1
= (-2-115.4) KJ/mol
= - 117.4 KJ/mol
Answer : - 117.4 KJ/mol
