Here are the steps.

(a) The order of the reaction

For the reaction $A \to Products$ $"A → Products"$ , the rate law is

$Rate = k {[A]}^{n}$ $"Rate" = k["A"]^n$

Use experiments 1 and 2 and the method of initial rates to determine the value
of $n$ $n$ .

(b) The rate constant

Insert your value of $n$ $n$ and the data from experiment 1 or 2 and calculate the value of $k$ $k$ at 25 °C.

Repeat for experiment 3 and calculate the value of $k$ $k$ at 35 °C.

(c) The activation energy

Use the rate constants at 25 °C and 35 °C to calculate $(Δlnk)/(Δ(1/T))$ .

$(Δlnk)/(Δ(1/T)) = "-"E_text(a)/R$

Then calculate $E_text(a)$ .
