Abstract
We make use of the Ehrenfest’s equations to explore the phase transition of a black hole with conformal anomaly The firstorder phase transition is ruled out because no discontinuity appears in entropy of the black holes We find that the phase transition of such black holes belongs to the second order subject to the Ehrenfest’s equations Further we also show that the secondorder phase transition will not happen for the black holes without conformal anomaly
