Question
2. Pure nickel exists in two solid forms Ni(a) (fcc) and Ni(B) (bcc). The enthalpy of transformation from a to B at atmospheric pressure is 1520 J/mole and the standard entropy (S°200) of Ni(a) is 29.8 J/mole.K. Calculate using the given data: a) the transition temperature and entropy of transformation (a to B) b) entropy of Ni(B) at 800 K. Ce (a) = 32.6 – 1.97 x 10° T-5.59 x 105T J/mole.K HT - Hzas (B) = - 9970 + 29.7 T+ 2.09 x 10 T? + 9.33 x 10° T' J/mole.K
