In which of the following values of kc,the reaction goes to completion in the forward direction;

2 answers

What following?
Refer to the problem above where kc = unity. If the reaction goes to completion then P will be very large and R will be very small so that K is a large number. Think about it this way.
If P is 2 and R is 1, then K = 2/1 = 2 and that means products are twice reactants. That is a forward reaction but not all that forward.
If P is 1,000.000 and R is 0.000,001 then K = 1E6/1E-6 = 1E12 and that is a reaction that has gone far to the right or very near completion.
