Question: An element transforms from a to at 773 K and 1 atm pressure with 912 J mol as enthalpy of transformation. The molar volumes

An element transforms from a to at 773 K and 1 atm

An element transforms from a to at 773 K and 1 atm pressure with 912 J mol as enthalpy of transformation. The molar volumes of a and phases are 7.377 cm and 7.317 cm, respectively. Assume that the difference in molar volumes of a and is independent of pressure. The pressure (in atm) required for a to transformation to occur at 723 K is (round off to nearest integer) (Given: 1 atm = 1.01325 105 Pa)
