Unformatted text preview: 2 , g ) = 213.74 J K !1 mol !1 ! S298.15 ( O2 , g ) = 205.138 J K !1 mol!1 The constant pressure heat capacities for of CO, CO2, and O2 are given by ! CP (CO, g ) = 29.14J K !1 mol!1 ! CP (CO2 , g ) = 37.13J K !1 mol!1 ! CP (O2 , g ) = 29.36J K !1 mol!1 Calculate !S ! for the reaction CO(g) + 1/2 O2(g) " CO2(g) at 475 K. Solution " 475 # ! ! ! !1 !1 !1 !1 !1 !1 S475 ( CO, g ) = S298 ( CO, g ) + CP ln $ % = 197.67 J K mol + ( 29.14 JK mol ) ( 0.47 ) = 211.26 JK mol & 298 ' " 475 # ! ! ! !1 !1 !1 !1 !1 !1 S475 ( CO...
