Q
Q: For a first-order reaction, if the half-life is 10 minutes, what will be the half-life if the concentration is doubled?
Solution:
The half-life of a first-order reaction is independent of concentration; it remains 10 minutes.
Steps: 5
Show Steps
Step 1: Understand what a first-order reaction is. In a first-order reaction, the rate of reaction depends only on the concentration of one reactant.
Step 2: Learn about half-life. The half-life is the time it takes for the concentration of a reactant to decrease to half of its initial value.
Step 3: Note that for first-order reactions, the half-life is constant and does not change with concentration.
Step 4: Since the half-life is given as 10 minutes, it will remain the same even if the concentration is doubled.
Step 5: Conclude that the half-life will still be 10 minutes.
