WORKBOOK PROBLEM 1 IN QUIZ 2 PREP 1

Postby Delacey Rodriguez 1D » Sun Jul 17, 2016 1:17 pm

A mixture initially consisting of 0.250 M N2(g) and 0.500 M H2(g) reaches equilibrium according to the equation N2(g) + 3H2(g) = 2NH3(g) (= means two arrows). At equilibrium, the concentration of ammonia is 0.150 M. Calculate the concentration of N2(g) at equilibrium.

I keep getting .275 instead of .175 like it says in the answer key. Can someone tell me what I'm doing wrong?

I am also getting the wrong answer. Do you use an ICE box for this problem or just straight up plug in the numbers and use the formula to find K.

The answer key is correct. ICE table would be recommended for this problem.
