Thank you all the answers are correct! thanks, Warrior Cat Lover! I got a 100 on my quick check
I tried doing that but the value was so high that I wanted to compare answers with something you would get DrBob222. My answer was something e^136
initial: I2 = 1.738 atm 2I = 0 change: I2 = -2x 2I = x equilibrium: I2 = 1.738 - 2x 2I = x so i set the equation as 0.254 = x/(1.738 - 2x) and i solved for x. i got 0.292 and after that how do i get % decomposition?
wrong..
for the last time i did it*
i did.. it was wrong for the last time
i don't understand..
thank youu!
