Consider the following reaction: a+b c +d a) what is the correct expression for the equilibrium constant (k)? b) the k value for this reaction is 45000. what does this tell you about the reaction? c) if the ris 45000 are the reactants more stable than the products?

a) k =

b) A value of 45000 means that tendency of your reaction is to have more products in a ratio of 45000:1

c) No, the products are more stable than reactants.

Explanation:

a) For a reaction:

A + B → C + D

The equlibrium constant (k) is:

k =

Where [x] is the molar concentration of x. Always the expression of equilibrium constant is molar concentration of products over molar concentration of reagents.

b) Having in mind the expression of equilibrium constant when k>1 the concentration of products is higher than concentration of reagents. Thus, when k<1 concentration of reagents is higher than concentration of products.

A value of 45000 means that tendency of your reaction is to have more products in a ratio of 45000:1

c) Again, a value of 45000 means that tendency of your reactants is react to produce products. Thus, the products are more stable than reactants.

I hope it helps!
