Question
Transcribed Image Text:We want to convert 18 g of solid water at-22 "C to vapor at 116 "C. The energy need for this process is supplied by combustion of CHJC,H. gas mixture which is composed of 60% CHalg) by mass.
What is the volume of required amount of the mixture at 25 °C and under 745 mmHg pressure?
For water
c(solid) = 2.11 Jg K, c(liquid) = 4.18 Jg" K, c(gas) = 2.00 Jg" K,
AH*(fusion) = 6.00 kl mol", AH(vapor.) = 40.7 kl mol".
For CH, AH"(combustion) = -891 kl mol
For C,H, AH"(combustion) = -1560 kl mol
