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 = -(ln(1-XA))/t
This formula uses 1 Functions, 3 Variables
Functions Used
ln - Natural logarithm function (base e), 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: 0.1 --> No Conversion Required
Reaction Time: 10 Second --> 10 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
k = -(ln(1-XA))/t --> -(ln(1-0.1))/10
Evaluating ... ...
k = 0.0105360515657826
STEP 3: Convert Result to Output's Unit
0.0105360515657826 1 Per Second --> No Conversion Required
FINAL ANSWER
0.0105360515657826 1 Per Second <-- Rate Constant for First Order Reaction
