In accordance with the equation r Ae QRT reaction rate incr

In accordance with the equation r = Ae -Q/RT, reaction rate increases with temperature in solid-state transformation reactions & above specific temperature ranges. The plot below demonstrates the (percentage transformation) versus the (logarithm of time) for an Austenite to Pearlite transformation, at 3 separate temperatures. Explain if this particular transformation reaction is in agreement with the above equation, or explain why not?

Solution

The slope of curve represents the reaction rate. From the plots, slope of the cuve decreases with increase in temperature. So this transformation is not in agreement with the given equation.
