Chapter 16.2, Problem 17SSC

Interpretation Introduction

Interpretation:

The effect of increasing temperature of 20K needs to be explained on the rate of reaction

Concept introduction:

Rate of a reaction is the speed at which the reactant changes into product. There are many factors which affects rate of a reaction, such as, nature of reactant, concentration of reactant, surface area of reactant, temperature etc.

Answer to Problem 17SSC

The rate of reaction quadruples, if temperature of 20 K is increased.

Explanation of Solution

When the temperature increases, the average kinetic energy of the particles of the substance also increases. So, reacting particles undergoes collision more frequently in higher temperature as compared to lower temperature. So, increase of temperature increases rate of a reaction. Given that, on increasing temperature of 10 K doubles rate of reaction, similarly increasing 20 K temperatures quadruples the reaction rate.

Conclusion

Increasing temperature leads to increase of rate of reaction.
