## Half Life of Second Order Reaction Solution

STEP 0: Pre-Calculation Summary
Formula Used
Half Life of Second Order Reaction = 1/Reactant Concentration*Rate Constant for Second Order Reaction
T1/2 = 1/CA*Ksecond
This formula uses 3 Variables
Variables Used
Half Life of Second Order Reaction - (Measured in Second) - Half Life of Second Order Reactions the time at which the concentration becomes half.
Reactant Concentration - (Measured in Mole per Cubic Meter) - The Reactant Concentration refers to the amount of reactant present in the solvent at any given point of time during the process.
Rate Constant for Second Order Reaction - (Measured in Cubic Meter per Mole Second) - The Rate Constant for Second Order Reaction is defined as the average rate of the reaction per concentration of the reactant having power raised to 2.
STEP 1: Convert Input(s) to Base Unit
Reactant Concentration: 0.1 Mole per Liter --> 100 Mole per Cubic Meter (Check conversion ​here)
Rate Constant for Second Order Reaction: 0.51 Liter per Mole Second --> 0.00051 Cubic Meter per Mole Second (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
T1/2 = 1/CA*Ksecond --> 1/100*0.00051
Evaluating ... ...
T1/2 = 5.1E-06
STEP 3: Convert Result to Output's Unit
5.1E-06 Second --> No Conversion Required
5.1E-06 5.1E-6 Second <-- Half Life of Second Order Reaction

## <Second Order Reaction Calculators

Time of Completion for different Products for Second Order Reaction
​ Go Time for completion = 2.303/(Rate Constant for Second Order Reaction*(Initial Reactant A Concentration-Initial Reactant B Concentration))*log10(Initial Reactant B Concentration*(Concentration at Time t of Reactant A))/(Initial Reactant A Concentration*(Concentration at Time t of Reactant B))
Rate Constant for different Products for Second Order Reaction
​ Go Rate Constant for First Order Reaction = 2.303/(Time for completion*(Initial Reactant A Concentration-Initial Reactant B Concentration))*log10(Initial Reactant B Concentration*(Concentration at Time t of Reactant A))/(Initial Reactant A Concentration*(Concentration at Time t of Reactant B))
Time of Completion for Same product for Second Order Reaction
​ Go Time for completion = 1/(Concentration at time t for second order*Rate Constant for Second Order Reaction)-1/(Initial Concentration for Second Order Reaction*Rate Constant for Second Order Reaction)
Rate Constant for Same Product for Second Order Reaction
​ Go Rate Constant for Second Order Reaction = 1/(Concentration at time t for second order*Time for completion)-1/(Initial Concentration for Second Order Reaction*Time for completion)

## Half Life of Second Order Reaction Formula

Half Life of Second Order Reaction = 1/Reactant Concentration*Rate Constant for Second Order Reaction

## What is Half Life of Reaction ?

Half-life of a chemical reaction can be defined as the time taken for the concentration of a given reactant to reach 50% of its initial concentration (i.e. the time taken for the reactant concentration to reach half of its initial value). It is denoted by the symbol ‘t1/2’ and is usually expressed in seconds.

## What is Second Order Reaction?

Second order reaction is a type of chemical reaction that depends on the concentrations of one-second order reactant or two first-order reactants.
