What does a large Keq value mean?
(1 point)
a Tendency to not obtain enough products in a reaction.
b Tendency to decrease the entropy in the system.
c Tendency of a reaction to proceed until all reactants turn into products.
Homework Answers
The large Keq means the concentration of products is much higher than the reactants. The reaction can be completed by the all or most of the reactants converting into the products. Therefore, option (c) tendency of a reaction to proceed until all reactants turn into products is correct.
