Half-life α 1/a(n-1) where n is:
Correct answer: D. Order of Reactions
- A. Number of reactant molecules
- B. Number of moles of reactants
- C. Number of moles of products
- D. Order of Reactions
Explanation
The formula for the half-life of a reaction, t1/2 = 1 / [A(a(n-1))], includes the term (n-1), where n represents the order of the reaction.

About Order of Reaction
Reaction order shows how the rate depends on the concentration of each reactant, as expressed in the rate law. Coverage includes zero, first and second-order reactions, integrated rate equations, half-life, units of rate constants and the distinction between overall order and molecularity.
