I had checked the last two options and the answer was wrong. The message said That the options I picked were the work done on the SYSTEM and NIT THE SURROUNDINDS.
Please help me understand how to figure how to figure that work is done in system vs. surrounding.
Also how to determine if work >0, W<0 etc.
Solution
System will do work on surrounding when system expands.
System will expand when there are more gases on product than reactant
option 1 has more gas on product side
option 2 has more gas on product side
option 3 has less gas on product side
option 4 has less gas on product side
Answer: option 1 and 2
