Chapter 18, Problem 8STP

Interpretation Introduction

Interpretation:

The fact towards which $K_{eq}$ being greater than one indicates is to be determined.

Concept introduction:

$K_{eq}$ is equilibrium constant.

It is the ratio of concentration of products to the concentration of reactants, each raising to power equal to the coefficient in the equation.

For equation,

$\begin{array}{l}A+B\to C+D\\ K_{eq}=\frac{\left[C\right]\left[D\right]}{\left[A\right]\left[B\right]}\end{array}$

Answer to Problem 8STP

B

Explanation of Solution

Equilibrium constant doesn’t give any information about rate of reaction.

If its value is greater than one, more products are formed at the equilibrium.

Conclusion

As Equilibrium constant doesn’t give any information about rate of reaction, options C and D are wrong. Option A is wrong because $K_{eq}$ is greater than one if products are more than reactants.
