The thickness of oxide film is y at time t. If K1, K2 and K3 are the temperature dependent constants, the parabolic law of oxidation is given by __________________?

(A)  y = k1 ln (k2t + k3) (X)
(B) y2 = 2k1t + k2 ()
(C)  y = k1 t + k2 (X)
(D) y = k1t3 + k2 (X)

Answers: The thickness of oxide film is y at time t. If K1, K2 and K3 are the temperature dependent constants, the parabolic law of oxidation is given by y2 = 2k1t + k2.
