Chemistry Help PLEASE!!
Got it! Thank you :)
Chemistry Help PLEASE!!
I think I realized what my mistake was, I assumed the reaction would go to the right, doesn't it go to the left?
Chemistry Help PLEASE!!
I don't know how to do this question, I understand we have to use ICE but I keep getting the wrong answer when I solve for x, it's just not working for me. Consider the following reaction: A(g) -> 2B (g) Find the equilibrium partial pressures of A and B for each of ...
