19. A group of scientists recently synthesis a brand-new compound, named as Q. Please use the following thermodynamic data to estimate the boiling temperature of Q at P = 1 bar. Here are thermodynamic data of Q at 25 °C, and it is assumed that and S° are independent of temperature. (A) 8442 K (B) 508.7 °C (C) 3818 K (D) 898.2 °C (E) There is not enough information.
