4. When studying scale formation on cobalt, the following values of the cobalt oxidation rate constant were obtained
t, ℃ 200 300 400
k, g^2/ 〖cm〗^4s 4.17*〖10〗^(-16) 4.03*〖10〗^(-14) 1.22*〖10〗^(-12)
t, ℃ 500 600 700
k, g^2/ 〖cm〗^4s 2.8*〖10〗^(-12) 8.05*〖10〗^(-12) 1.33*〖10〗^(-11)
Graphically determine the energy of the scaling process
