Find out the value of Kc for each of the following equilibria from the value of Kp:
2NOCl(g) rightwards harpoon over leftwards harpoon2NO(g) + Cl2(g);     Kp = 1.8 x 10-2 at 500 K

Solution

2 NOCl space left parenthesis straight g right parenthesis space rightwards harpoon over leftwards harpoon space 2 NO space left parenthesis straight g right parenthesis space plus Cl subscript 2 space left parenthesis straight g right parenthesis straight K subscript straight p space equals 1.8 space straight x space 10 to the power of negative 2 end exponent increment straight n subscript straight g space equals 3 minus 2 equals 1 straight K subscript straight p space equals straight K subscript straight c left parenthesis RT right parenthesis to the power of increment straight n end exponent space equals straight K subscript straight c left parenthesis RT right parenthesis straight K subscript straight c equals straight K subscript straight p over RT space equals fraction numerator 1.8 space straight x space 10 to the power of negative 2 end exponent over denominator 0.0831 space straight x space 500 end fraction space equals 4.33 space straight x 10 to the power of negative 4 end exponent
