Chapter U5.13, Problem 9E

Interpretation Introduction

Interpretation:

The reason for the happening explosion so quickly needs to be explained.

Concept introduction:

For a reaction to occur, the collision of reactant particles in the correct orientation with sufficient energy is required. The rate of a reaction is the speed at which a reaction occurred.

Answer to Problem 9E

Energy is released in explosion reactions thus explosion occurs rapidly.

Explanation of Solution

All chemical reactions need some input energy to get started. Once an exothermic reaction started, it provides the necessary energy to the reactant molecules. During an explosion, a large quantity of energy is released from chemical bonds very quickly. The released energy supplies activation energy to other molecules and causes a very rapid explosion.

Conclusion

Reactions in which energy is released, the released energy supplies activation energy to the reactants and thus reaction occur rapidly.
