When barium carbonate dissociates according to the reaction, BacO; (s) = Bao (s) + CO2 (g) the pressure of CO2 g) in equilibrium with the solid phases is 7.0x10-2 bar at 1400 K and 0.37 bar at 1500 K. Use this information to calculate A,H°, A,G° and 4,5° at 298.15 K. You may assume that 4,H° is independent of temperature.

Part A The value of K, for nitrous acid (HNO,) at 25 °Cis 4.5 x 10 4 Part B Part C What is the value of AG at equilibrium? Express your answer using one significant figure. AG = 0 kJ Submit Previous Answers v Correct By definition, the Gibbs free energy of a reaction is zero when it is at equilibrium. Forward and reverse reactions continue to occur dynamically, but there is Part D What is the value of AG when [H'] = 5.1 x 10 2 M. [NO,] = 6.2 x 10 4M and (HNO2] = 0.21 M? Express your answer using three significant figure. ? AG = kJ Submit Previous Answers Request Answer X Incorrect; Try Again; 5 attempts remaining

For the following reaction: A(g) + B(g) = 2 C(a) Calculate the magnitude of K, (don't report the units) assuming the following composition at equilibrium: PA = 0.438 bar PB = 0.716 bar Pc = 0.122 bar

Calculate the equilibrium constant at 37°C for the reaction  Glucose +6O2 + 36ADP + 36Phosphate -> 6CO2 + 42H2O + 36ATP Change in G°= -423kcal/mole of Glucose

What is the A,G for the following reaction (in kJ mol ¹) at 298 K? 2 Si (s) + 3 H2(g) Si₂H6 (g) 1 The conditions for this reaction are: PH2 = 1.21 bar PsizH6 = 0.5 bar. You will also need to use Appendix II in your textbook (containing standard Gibbs energies of formation). A copy of Appendix II has also been posted on eClass. Please use the method of Gibbs energy of formation to calculate ArG" if needed. For partial credit, enter the value of "Q" for this reaction. Answer:
