14.8 Thermal decomposition of sodium bicarbonate is given by the following re- action: 2NAHCO3 (s) Na2CO3...
4 Look at the decomposition reaction for Marks: 2 sodium bicarbonate. 2NaHCO3(s) Na2CO3(s) + H2O(g) + CO2(g) Suppose that triangle H = 64.5 kJ/mol and triangleS = 0.167kJ/mol.K. Which statement about this reaction is correct? Assume that triangleH and triangleS are constant for all the given temperatures. Choose one answer a. The reaction is spontaneous at 327 K. b. The reaction is spontaneous at 380 K. c. The reaction is at equilibrium at about 386 K. d. The reaction is...
Sodium carbonate can be made by heating sodium bicarbonate: 2NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) Given that ΔH° = 128.9 kJ and ΔG° = 33.1 kJ at25°C, above what minimum temperature will the reaction becomespontaneous under standard state conditions?
8. Sodium bicarbonate, NaHCO3, undergoes thermal decomposition according to the reaction: 2 NaHCO3 (s) + Na2CO3 (s) + CO2 (g) + H20 (g). How does the equilibrium position shift as a result of each of the following disturbances? a. 0.20 atm argon is added. b. NaHCO3 (s) is added. c. Mg(CIO)2 is added as a drying agent to remove H2O vapor. d. Dry ice (Solid CO2) is added. e. The volume of the container decreases. f. The temperature of the...
sodium carbonate can be made by heating sodiumbicarbonate: 2NaHCO3(s) --> Na2CO3(s) +CO2(g) + H2O(g) Given that ΔHo = 128.9 kJ/mol andΔGo = 33.1 kJ/mol at 25oC, above whatminimum temperature will the reaction become spontaneous understandard state conditions? I know the answer is 401 K but I don't know how to get theanswer. If you could please show me step by step I will ratelifesaver.
