NaHCO, decomposes to sodium carbonate, water vapor, and carbon dioxide

NaHCO, decomposes to sodium carbonate, water vapor, and carbon dioxide. 100 g of the reactant is placed in a 5-L container, and the temperature is raised to 433 K. (20 pts. total) a) Show the balanced reaction. b) The total pressure in the container at 433 K is 7.76 atm once equilibrium is reached. Calculate the number of moles of water vapor present at equilibrium. c) Write the equilibrium expression for K, and calculate its value at 433.K. d) Use LeChatelier's principle to predict what would happen to the partial pressure of carbon dioxide in the container if the container's volume were decreased. e) Calculate K. for this reaction.
