1. a) Calculate the value of standard molar enthalpy and entropy of the chemical reaction at 298K using the data given: Is the chemical reaction exothermic reaction or not? WHY? ZrO2()+2CO(g)Zr()+2CO2(g)at298K b) Calculate the enthalpy and entropy of chemical reaction at 1600K. Organize them as we do it in the class. Do not calculate the values! ZrO2()+2CO(g)Zr()+2CO2(g)at1600K DATA: HZr()=3900 joules at 1136K, HZrO2()=5900 joules at 1478K Standard molar enthalpy formation and entropy at 298K: HfZrO2()=1,100800joules,SZr()=39J/K,SZrO2()=50.4J/K,HrCO(g)=110500J,SCO(g)=197.5J/K,HfCO2(g)=393500J,SCO2(g)=213.7J/K
