Calculation of the Rate of the Elementary Reaction
The given elementary reaction is 2A + B → 3C. The rate of appearance of C at time 't' is 1.3×104 mol-1 s-1. The rate of the reaction can be calculated as follows:
Rate of the reaction = (1/3) × (d[C]/dt) = (1/3) × (1.3×104 mol-1 s-1) = 4.33×103 mol-1 s-1
Therefore, the rate of the reaction at time 't' is 4.33×103 mol-1 s-1.
Calculation of the Rate of Disappearance of A
The stoichiometric coefficient of A in the given reaction is 2. Hence, the rate of disappearance of A can be calculated as follows:
Rate of disappearance of A = (-1/2) × (d[A]/dt) = (-1/2) × (1.3×104 mol-1 s-1) = -6.5×103 mol-1 s-1
Therefore, the rate of disappearance of A at time 't' is -6.5×103 mol-1 s-1.
Explanation
The rate of an elementary reaction is determined by the rate constant and the concentrations of the reactants raised to their stoichiometric coefficients. In the given reaction, the stoichiometric coefficient of C is 3, and hence the rate of appearance of C is directly proportional to the rate of the reaction. Therefore, the rate of the reaction can be calculated by dividing the rate of appearance of C by the stoichiometric coefficient of C. Similarly, the rate of disappearance of A can be calculated by multiplying the rate of appearance of C by the stoichiometric coefficient of A and dividing by its stoichiometric coefficient.
