(6x+1)(1-3x) It is known that the kinetics of recrystallization for some alloy obey the Avrami equation andthat the value of n in the exponential is 2.5. If, at some temperature, the fraction recrystallized is0.40 after 200 min, determine the rate of recrystallization at this temperature. If the government requires a natural monopoly to price at marginal cost, Group of answer choices monopoly firms will earn zero economic profits because the price of the good equals the cost of producing that good. monopoly firms will operate at a loss because P < AC. more firms will be able to enter the market. producer surplus will increase because quantity supplied is greater.
