This is a question on Non-standard states.

Calculate ¥ÄG605 for the following reaction under the given conditions. Use data obtained from the table below and assume that ¥ÄHo and ¥ÄSo do not vary with temperature.
C2H4(g) + H2O(g) ¡æ C2H5OH(g)

The ¥ÄHo and ¥ÄSo values as well as the partial pressure values are given for each substance in gas form. I am not sure how the partial pressure is invovled in calculating G value.

Thanks

nevermind, i figured this one out!
