WebWe show that the first law and the WCCC are valid for all spacetime dimensions (D) independent of the choice of the parameters characterizing the black holes. But to verify the second law in the extremal and non- extremal configurations one has to be very cautious as it gets strongly affected by the choices of the values of the black hole parameters and …
