Here are the steps.

(a) The order of the reaction

For the reaction #"A → Products"#, the rate law is

#"Rate" = k["A"]^n#

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

(b) The rate constant

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

Repeat for experiment 3 and calculate the value of #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)#.
