The conversion of a reactant, undergoing a first order reaction, at a time equal to three times the half life of the reaction is ?
Correct answer: A. 0.875
- A. 0.875
- B. 0.5
- C. 0.425
- D. Data insufficient to calculate
Explanation
After three half-lives, the unreacted fraction is (1/2)^3 = 1/8. Hence the conversion is 1 − 1/8 = 7/8 = 0.875.
