Answer» 2.7 kcal `-2.7 kcal` 9.3 kcal `-9.3kcal` Solution :`DeltaH=DeltaU+Deltan_(G) RT` Given`:DeltaU =2.1 kcal ,Deltan_(f) = 2-0=2`, `R = 2 xx 10^(-3) kcal, T= 300K` `:. DeltaH =2.1+ 2 xx 2XX 10^(-3) xx 300 = 3.3 kcal` Again, `DeltaG= DeltaH - T DELTAS` Given `: DeltaS =20 xx 10^(-3) kcal K^(-1)` `DeltaH= 3.3 kcal` ( calculateabove) `:. DeltaG = 3.3 - 300 xx (20 xx 10^(-3))` `=3.3-6 = - 2.7 kcal`
