362.51 Kelvinln (p1/p2) =( dH / R) (1/T2 - 1/T1)ln (760 Torr /520Torr) =( 40,700 Joules / 8.314 J molâ’1K-1)(1/T2 - 1/373K)ln (1.4615) =( 4895.35)(1/T2 - 0.002681)0.37946 = 4895.35/T2 - (0.002681)(4895.35)0.37946 = 4895.35/T2 - (13.124)0.37946 + 13.124 = 4895.35/T213.5039 = 4895.35/T2T2 = 4895.35 / 13.5039T2 = 362.51answer is 362.51 Kelvin- 273answer is also 89.5 Celsius
