HW 2. Due: 10/28/11 NO CREDIT WILL BE GIVEN IF WORK IS NOT SHOWN!! Problems (all from the textbook) 6.1 Calculate Δ H 1600 and Δ S 1600 for the reaction Zr ( β ) + O 2 = ZrO 2( β ) 6.2 Which of the following two reactions is more exothermic? 1. C (graphite) + (1/2)O 2(g) -> CO (g) at 1000 K 2. C (diamond) + (1/2)O 2(g) -> CO (g) at 1000 K 6.3 Calculate the change in enthalpy and the change in entropy at 1000 K for the reaction CaO (s) + TiO 2(s) -> CaTiO 3(s) 6.4 Copper exists in the state T = 298 K, P = 1 atm. Calculate the temperature to which the copper must be raised at 1 atm pressure to cause the same increase in

Unformatted text preview: molar enthalpy as is caused by increasing its pressure to 1000 atm at 298 K. The molar volume of Cu at 298 K is 7.09 cm 3 , and the thermal expansivity is 0.493 * 10-3 K-1 . These values can be taken as being independent of pressure in the range 1 1000 atm. These problems need some constants and equations provided at the back of the book. If you do not have the book yet, please let me know through email...
