Question

Given the equilibrium: A+B <--> C. The greatest concentration of C would be produced if the equilibrium constant of the reaction is equal to
a. 1x10^-9
b. 1x10^9
c. 1x10^-3
d. 1x10^3

Answer 1

Answer: The greatest concentration of C would be produced if the equilibrium constant of the reaction is equal to $1\times 10^9$

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as $K_c$

For the given chemical reaction:

$A+B\rightarrow C$

The expression for $K_c$ is written as:

$K_c=\frac{[C]}{[A][B]}$

Thus higher is the value of $K_c$ , higher will be the concentration of C. Thus the greatest concentration of C would be produced if the equilibrium constant of the reaction is equal to $1\times 10^9$
