Chapter U5.106, Problem 2E

Interpretation Introduction

Interpretation: The name of three things needs to be written due to which rate of reaction between two solids can be increased.

Concept introduction: Rate of a reaction is the speed at which a reaction takes place. There are many factors that affect the rate of a chemical reaction, such as, temperature, concentration, surface area etc.

Answer to Problem 2E

Three things due to which rate of reaction between two solids can be increased are,

Increase of temperature, increasing concentration and increase of surface area.

Explanation of Solution

Increasing temperature results increase of the average kinetic energy of reactant molecules. This results the rapid movement of particles and hence more collision occurs.

Reaction rate also increases if the concentration of reactants is more. More reactants in small volume results more collision. Surface is another factor that affects rate. Increase of surface area results increase of speed of reaction.

Conclusion

Many factors affects the rate of chemical reaction, such as, concentration, temperature etc.
