Calculating the Rate Constant of a Reaction
Heading: Introduction
The passage talks about the hydrogenation of ethene to form ethane and the rate constant of the reaction.
Heading: Rate Law Equation
The rate law equation for the given reaction can be written as:
Rate = k [C2H4]
Heading: Given Information
From the passage, we know that:
- The rate constant, k = 2.5 × 10–15s–1
- The concentration of the reactant reduces to one-third of the initial concentration in 5 minutes
Heading: Solution
We can use the following equation to calculate the rate constant after 5 minutes:
ln [A]t/[A]0 = -kt
Here, [A]t is the concentration of the reactant at time t, [A]0 is the initial concentration of the reactant, k is the rate constant, and t is the time.
Substituting the given values, we get:
ln (1/3) = -k x 5
Solving for k, we get:
k = (ln 3)/(5 x 60) = 0.2197 min–1
Heading: Answer
Therefore, the rate constant of the reaction after 5 minutes is 0.2197 min–1, which is option 'C'.
