Answer is different for 5G.15

[Tiffany Chao 2H]

I keep getting -2.7 kJ/mol as my answer. However, the book says -27 kJ/mol. Is anyone else getting the same answer as me or did I just calculate something wrong.

Thanks

I keep getting -2.7 kJ as well. Can someone explain what we are doing wrong?

I also keep getting -2.7kJ. Not sure how it is supposed to be -27 honestly.

I also got -2.7 kJ/mol. For -RTlnK I got -12349.86 J/mol, and for RTlnQ I got 9612.98 J/mol, so shouldn't their sum be -2736.87 J/mol or -2.7 kJ/mol?

I got -27 kJ/mol as my answer.
