First Order Reaction: Overview, Questions, Preparation

The order of first order reaction is equal to 1.

The rate of a first-order reaction can be described using the following equation:

rate = k[A]^m

where:

• rate is the rate of the reaction
• k is the rate constant of the reaction
• [A] is the concentration of the reactant, A
• m is the order of the reaction (in this case, m = 1, since the reaction is first order)

The rate constant (k) is a constant value that depends on the specific reaction and is related to the frequency of the successful collisions between the reactants.

First-order reactions are typically characterized by a single inflection point, and the reaction rate increases as the reactant concentration increases.

The reaction of hydrogen gas with oxygen gas to form water:

2H₂ + O₂ → 2H₂O

This reaction is a first-order reaction, as the rate of the reaction increases with the concentration of hydrogen gas.

The decomposition of hydrogen peroxide:

2H₂O₂ → 2H₂O + O₂

This reaction is also a first-order reaction, as the rate of the reaction increases with the concentration of hydrogen peroxide
