Lesson 1: Equilibrium constant

Writing equilibrium constant expressions

You might need: Periodic table

What is the equilibrium constant expression K, start subscript, start text, c, end text, end subscript for the following balanced equation?

start text, P, b, C, l, end text, start subscript, 2, end subscript, left parenthesis, s, right parenthesis, \rightleftharpoons, start text, P, b, end text, start superscript, 2, plus, end superscript, left parenthesis, a, q, right parenthesis, plus, 2, start text, C, l, end text, start superscript, minus, end superscript, left parenthesis, a, q, right parenthesis

(Choice A)
start fraction, open bracket, start text, P, b, end text, start superscript, 2, plus, end superscript, close bracket, open bracket, start text, C, l, end text, start superscript, minus, end superscript, close bracket, squared, divided by, open bracket, start text, P, b, C, l, end text, start subscript, 2, end subscript, close bracket, end fraction
(Choice B)
start fraction, open bracket, start text, P, b, C, l, end text, start subscript, 2, end subscript, close bracket, divided by, open bracket, start text, P, b, end text, start superscript, 2, plus, end superscript, close bracket, open bracket, start text, C, l, end text, start superscript, minus, end superscript, close bracket, squared, end fraction
(Choice C)
start fraction, 1, divided by, open bracket, start text, P, b, end text, start superscript, 2, plus, end superscript, close bracket, open bracket, start text, C, l, end text, start superscript, minus, end superscript, close bracket, squared, end fraction
(Choice D)
open bracket, start text, P, b, end text, start superscript, 2, plus, end superscript, close bracket, open bracket, start text, C, l, end text, start superscript, minus, end superscript, close bracket, squared
