Chapter 16, Problem 50A

Interpretation Introduction

Interpretation:

To identify the role that reactivity of the reactants plays in determining the rate of a chemical reaction.

Concept introduction:

Rate of a reaction 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 50A

Surface area, temperature catalyst or inhibitors, reactivity, concentrations of the substance are the things which affect the rate of reaction of a chemical reaction. Reaction will be slower if the substance is not reactive and reaction will be very high if the substance is reactive.

Explanation of Solution

At a given time rate of a reaction will depend upon concentration of reactant at that time. Concentration of reactant keeps on falling with time as reaction progresses. Temperature, surface area, catalyst or inhibitors, reactivity, concentrations of the substance are the things which affect the rate of reaction of a chemical reaction.

Substance that reacts during a reaction is indicated by the reactivity of a substance. Reaction will be slower if the substance is not reactive and reaction will be very high if the substance is reactive.

Conclusion

Reaction will be very high if the substance is reactive and reaction will be slower if the substance is not reactive.
