Hope you understand how to work out those types of questions now xD ;)
The half-life of the reaction is 50 minutes
Data;
- Time = 43 minutes
- Type of reaction = first order
- Amount of Completion = 45%
Let the initial concentration of the reaction be X
The reactant left = (1 - 0.45) X = 0.55 X
= X
For a first order reaction
The half-life of a reaction is said to be the time required for the initial amount of the reactant to reach half it's original size.
Substitute the values
The half-life of the reaction is 50 minutes
