What is the half-life of a first-order reaction? First Order Reaction: First order reaction is a reaction whose rate is directly proportional to molar concentration of the reactant, raised to power one. If r is the rate of a first order reaction and {eq}[A]{/eq} is molar concentration...
The order of a reaction in some species seems an obvious, trivial concept that all chemists master. However, in complex situations such as catalytic systems, the order of a reaction is not always that simple: it can be partial, negative and function of other parameters. In order to analyze...
What is the lifetime of a first-order reaction with a rate constant of 5.20?x10^-4 * s^-1? Half-life: The half-life of a reaction describes the initial concentration of a reactant reduced to its half value. It is expressed by symbol {eq}t_{{1}/{2}} ...
To solve the problem of finding the half-life of a first-order reaction given that 70% of the reaction was completed in 70 minutes, we can follow these steps:Step 1: Understand the given data We know that 70% of the reaction is

Order of reaction: The sum of concentration terms on which the rate of a reaction actually depends as observed experimentally is called the order of the reaction i.e. the sum of the powers or exponents to which the concentration or pressure terms are raised in order to determine the rate ...
