Formula for Time Required for Completion of 99% of a First Order Reaction
The time required for the completion of 99% of a first-order reaction is given by the following formula:
t = 4.606/k
Explanation
- The rate constant (k) for a first-order reaction is a constant that determines the rate of the reaction.
- The first-order reaction follows exponential decay, and the rate of the reaction is directly proportional to the concentration of the reactant.
- The half-life of a first-order reaction is constant, and the time required for the concentration of the reactant to decrease to half of its initial value is given by t1/2 = 0.693/k.
- To find the time required for the completion of 99% of the reaction, we need to find the time required for the concentration of the reactant to decrease to 1% of its initial value.
- Using the equation for the half-life, we can find the time required for the concentration to decrease to 1% of its initial value as follows:
t = t1/2 * log(1/0.01) = 4.606/k
Therefore, the time required for the completion of 99% of a first-order reaction is given by the formula t = 4.606/k.
