Question

4. What is Au of water for a temperature change from 298 to 363 K. Over this temperature range the molar entropy of water is given by Sm = a + bТ where a = 1.5 J K-' mol-and b = 0.23 J K-2 mol-1.

Answer 1

By integrating the relations upto given limits we can find out the final values.for better understanding please go through the solution....thanks

tion since we know that 12.38 T = 263k By inte rating both side PT P Jolly - simdT 6= 0.23 Ik mot = faldly --sä + DAT {a (T2-T,) + b (T22 - T, ²)} -- $1.5 J kant 363-298) K + 0.23 Jkt mit (363² - 298² K²} =-115 x 65 Jan 0.23 42965 Imit"} -_-137.5 + 49409753 --5038.475 Juni Therefore or die water for a temperature 1298 to 363k --5038 475 Juni m-5.04 Kimni
