Chapter 16, Problem 51A

In general, what is the relationship between reaction rate and reactant concentration?

Interpretation Introduction

Interpretation:

To identify the relationship between reaction rate and reactant concentration.

Concept introduction:

Reaction rate is the change in the amount of products or reactants per unit time.

$\text{Rate}=\frac{-\text{Change}\text{in}\text{reactants}}{\text{Change}\text{in}\text{time}}$

Answer to Problem 51A

Rate of a reaction increases on increasing reactant concentration.

Explanation of Solution

In a chemical reaction surface area, temperature catalyst or inhibitors, reactivity, concentrations of the substance affects rate of reaction.

Rate of a reaction increases on increasing reactant concentration. To form reaction products extra reacting ions or molecules are present. Rate of a reaction decreases on decreases reactant concentration. Reactant concentration affects rate of a reaction.

Conclusion

Reactant concentration affects rate of a reaction and relationship is not simple.
