What is the reaction quotient?
C(s) + H20(g) ---> CO(g)+H2(g)
If during the course of the reaction, the vessel is found to contain 5.75 mol of C, 13.5 mol of H2O, 3.20 mol of CO , and 6.90 mol of H2, what is the reaction quotient?
Answer:
Q = [CO] [ H2 ] / [ H2O]
[ CO] = 3.20 / 3.25 = 0.985 M
[ H2 ] = 6.90 / 3.25 = 2.12 M
[H2O ] = 13.5 / 3.25 = 4.15
C is solide and we can not put it in the expression
Q = 0.985 x 2.12 / 4.15 = 0.503
