Expert Solution
Step 1
The given graph represents a first order reaction. The initial concentration of reactant is 0.8 and half of the initial concentration of the reactant equals 0.4 mol/L. The time consumed by the reaction to half the initial concentration value is called as half-life and the value of half-life in this case is 0.2 second.
The rate constant of the reaction (k) is equal to 0.693/0.2 = 3.5 s-1 (two significant digits)
