The steady-state creep activation energy is given by the Arrhenius type rate equation ε = Ae-(Q/RT), where, Q = activation for rate-controlling step A = pre-exponent complex constant containing the frequency of vibration of the flow unit T = absolute temperature R = Universal gas constant The slope of the equation for log ε vs. log T plot will be equal to __________

Correct Answer: Q/2.3R
The equation is ε = Ae-(Q/RT) Taking log on both sides, log ε = Q/eRT log A The slope will be given by the Q/eR; where the value of e=2.3 So, the slope of the equation will be equal to Q/2.3R.
