Half Time Completion of First Order Reaction Solution

STEP 0: Pre-Calculation Summary

Formula Used

Half Time = 0.693/Rate Constant for First Order Reaction
t_1/2 = 0.693/k_first
This formula uses 2 Variables

Variables Used

Half Time - (Measured in Second) - The Half Time of the reaction is the time at which the concentration of reactant is exactly half of the initial concentration.
Rate Constant for First Order Reaction - (Measured in 1 Per Second) - The Rate Constant for First Order Reaction is defined as the rate of the reaction divided by the concentration of the reactant.

STEP 1: Convert Input(s) to Base Unit

Rate Constant for First Order Reaction: 0.520001 1 Per Second --> 0.520001 1 Per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_1/2 = 0.693/k_first --> 0.693/0.520001

Evaluating ... ...
