For the reaction c (s) + h2o (g) → co (g) + h2 (g) δs°sys = 133. 6 j/mol k; and δh°sys = 131. 3 kj/mol at 298k; at temps greater than °c, this reaction is spontaneous. Do not include units in your answer.

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's.
