Question

The reaction is called chain reaction when

a. it is one that can be initiated by light

b. it involves free radicals that have an unusual stability and thereby cause a large quantum yield

c. it involves a series of steps, each of which generates a reactive intermediate that brings about the next step

d. it involves several steps

e. it involves two steps of equal activation energy

Answer 1

c. it involves a series of steps, each of which generates a reactive intermediate that brings about the next step

Step-by-step explanation:

A chain reaction consist of many repeating steps. Chain reaction will never stop until all the reactant has been exhausted. It is more of a cycle of reaction that generate a reactive intermediate that brings about the next step.

Example of a chain reaction is the chlorination of methane.

CH4 + Cl2 ↔ CH3Cl + HCl

CH3Cl + Cl2 ↔ CH2Cl2 + HCl

CH2Cl2 + Cl2 ↔ CHCl3 + HCl

CHCl3 + Cl2 ↔ CCl4 + HCl
