Rate Constant for First Order Irreversible Reaction Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rate Constant for First Order Reaction = -(ln(1-Reactant Conversion))/Reaction Time
K_{1st order} = -(ln(1-X_A))/t
This formula uses 1 Functions, 3 Variables

Functions Used

ln - The natural logarithm, also known as the logarithm to the base e, is the inverse function of the natural exponential function., ln(Number)

Variables Used

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.
Reactant Conversion - Reactant Conversion gives us the percentage of reactants converted into products. Enter the percentage as a decimal between 0 and 1.
Reaction Time - (Measured in Second) - Reaction Time is the time taken to complete a reaction to a certain extent.

STEP 1: Convert Input(s) to Base Unit

Reactant Conversion: 0.8 --> No Conversion Required
Reaction Time: 7.2 Second --> 7.2 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_{1st order} = -(ln(1-X_A))/t --> -(ln(1-0.8))/7.2

Evaluating ... ...

K_{1st order} = 0.223533043393625

STEP 3: Convert Result to Output's Unit

0.223533043393625 1 Per Second --> No Conversion Required

FINAL ANSWER

0.223533043393625 ≈ 0.223533 1 Per Second <-- Rate Constant for First Order Reaction
