In a first order reaction, the time required to reduce the concentration of reactant from 1 mole/litre to 0.5 mole/litre will be ______________ that required to reduce it from 10 moles/litre to 5 moles/litre in the same volume ?
Correct answer: C
Explanation
For a first-order reaction, the time taken to reduce concentration by half (half-life) is constant and does not depend on the initial concentration.
