試題 :
consider the reaction:2NaHCO3→ NaCO3(s)+H20(g)+CO2(g).if 10.0g of NaHCO3
←
is placed in a 1.00L container at 100'C,it exerts a total pressure of 1.60atm
answer the following questions(Na=23.0,C=12.0,O=16.0)
1.find the equilibrium constant (Kp) for the reaction at 110'C
2.calculate the percentage of unreacted NaHCO3 at equilibrium
3.find the equilibrium constant(Kc) for the reaction at 110'C
4.if the temperature is raised to 120'C,the total pressure is increased to
4.00atm. find Kp at 120'C
5.estimate △H' for the reaction
6.estimate the vapor pressure of water at 90'C △H'vap =40.0kJ/mol
7.if the container is cooled to 90'C,find the total pressure of the system?
