The reaction N2(g) + 3H2(g) ⇌ 2NH3(g) has KC = 0.500 at 400*C. Write the reaction quotient (QC) expression including the “i” subscripts. Then, find the value for QC if [N2] = 0.015 M, [H2] = 0.12 M, and [NH3] = 0.00054 M. Compare this value with KC and determine which direction the reaction will go towards.
