Answer : The initial rate of the reaction is,
Explanation :
First we have to calculate the rate constant of the reaction.
Expression for rate law for first order kinetics is given by :
where,
k = rate constant = ?
t = time taken for the process = 44 s
= initial amount or concentration of the reactant = 0.1108 M
= amount or concentration left time 44 s = 0.0554 M
Now put all the given values in above equation, we get:
Now we have to calculate the initial rate of the reaction.
Initial rate = K [A]
At t = 0,
Initial rate = 0.0157 × 0.1108 =
Therefore, the initial rate of the reaction is,
