Order of Reaction:
The order of reaction refers to the relationship between the rate of a chemical reaction and the concentration of the reactants. It is determined experimentally and is represented by an integer or a fraction.
In this given passage, it is stated that the rate of the reaction is proportional to the concentration of the reactant. This implies that the reaction follows a first-order kinetics.
Explanation:
To determine the order of reaction, we can use the given information about the reduction in concentration of the reactant over time.
The concentration of the reactant reduces to one-third of the initial concentration in 5 minutes. Let's assume the initial concentration of the reactant is 'A'. After 5 minutes, the concentration of the reactant becomes 'A/3'.
Now, using the rate constant (k) and the given information, we can determine the order of reaction.
The rate equation for a first-order reaction is given by:
Rate = k[A]
Since the rate of the reaction is proportional to the concentration of the reactant, we can write:
Rate = k * (A/3)
Now, let's compare the rates at two different times:
Rate1 = k * A (initial rate)
Rate2 = k * (A/3) (rate after 5 minutes)
According to the given information, the concentration reduces to one-third of the initial concentration after 5 minutes. Therefore, the rate of the reaction after 5 minutes is one-third of the initial rate.
Rate2 = (1/3) * Rate1
From the above equation, we can see that the rate of the reaction is directly proportional to the concentration of the reactant. This confirms that the reaction follows a first-order kinetics.
Hence, the correct answer is option 'B' - First order.
