Solve correctly please
The activation energy, E,, is the minimum energy required by the reactants to form the products. It is determined by measuring the rate constant at
various temperatures.
The plot of In(k) (y) versus 1/T (x) should yield a straight line with the slope --E/R (R-8.314 J K mol¹),
For the decomposition of H₂O₂:
