Problem- At equilibrium, the concentrations in this system were found to be [N2]=[O2]=0.200 M and [NO]=0.400 M.
N2(g)+)2(g) <=> 2NO(g)
If more NO is added, bringing its concentration to 0.700 M, what will the final concentration of NO is after equilibrium is re-established?
Please define why you think that's the right answer
