Equilibruim Assessment

[beckyolmedo1G]

A mixture initially consisting of 0.250 N2 (g) and 0.500 M H2 (g) reacts to form NH3 (g) which is 0.15 M NH3 (g) at equilibrium. Calculate the concentration of N2 (g) at equilibrium for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g)

can someone help me find the concentration of N2? Above is everything that is given in the problem.

You should try using an ICE chart using the initial concentrations given as well as the concentration of NH3 at equilibrium. Hope this helps!

Thank you!!

don't forget if the x value is very small (i.e. less than 10^-3) you can ignore the x when subtracting it from another value!

[Jacqueline Duong 1H]

to add on to the x being small, if it is less than 5% of the initial value, then x is negligible when adding or subtracting from a number

I thought if K is less than 10^-3 then we can estimate? Not x?
