Question 15
XE-CNAT2 marksNeeds review
An element transforms from α to β at 773 K and 1 atm pressure with 912 J mol
as enthalpy of transformation. The molar volumes of α and β phases are 7.377 cm
and 7.317 cm
, respectively. Assume that the difference in molar volumes of α and β is independent of pressure. The pressure (in atm) required for α to β transformation to occur at 723 K is ________ (round off to nearest integer)(Given: 1 atm = 1.01325 × 10⁵ Pa)
