Increase the value of the equilibrium constant, K B. The equilibrium constant kc for the equation CS2 + 4H2 CH4 +2H2S at 900 C is 27.8. what is the value of kc for the following equation? A 10.0-g sample of solid NH4Cl is heated in a 5.00-L container to 900.°C. Question: The equilibrium constant Kc for the equatino CS2(g)+ 4H2(g) goes to CH4(g)+2H2S(g) at 900 degree's C is 27.8. Estimate the value of the equilibrium constant at 550 K for each of the following reactions. So for aA + bB ==> cC + dD you've ok = [C]^c[D]^d/[A]^a[B]^b. Shift the equilibrium to the right B. You have done the calculation correctly, but what you have calculated isn't Kc, it is Q, or the "Reaction Quotient", which is a measure of the extent of a reaction subject to dynamic equilibrium. i know that [CH4] goes up, [H2S] goes up, [CS2]goes down and [H2] goes down. A. I'm not sure what to do. Please explain step by step so i can understand thanks! Question: The equilibrium constant Kc for the equatino CS2(g)+ 4H2(g) goes to CH4(g)+2H2S(g) at 900 degree's C is 27.8.

If anyone can help it would be great! Write the equilibrium constant expressions (Kc) for the following reactions: (a) CO (g) + H2O (g) ⮂ CO2 (g) + H2 (g) (b) CH4 (g) + 2H2S (g) ⭢ CS2 (g) + 4H2 (g) (c) COCl2 (g) ⮂ Cl2 (g) + CO (g) (d) 2HI (g) ⮂ H2 (g) + I2 (g) (e) PCl3 + Cl2 (g) ⮂ PCl5 (g) (f) 2H2 (g) + O2 (g) ⮂ 2H2O (l) (g) 3Ca2+ (aq) + 2PO43- ⮂ Ca3(PO4)2 (s) 1B. Sample Problem 17.10 Predicting Reaction Direction and Calculating Equilibrium Concentrations PROBLEM: Given the reaction: CH4(g) + 2H2S(g) CS2(g) + 4H2(g) In one experiment, 4.0 M of CH4, 4.0 M of CS2, 8.0 M of H2S, and 8.0Mof H2 are initially mixed in a vessel at 9600C. A. Precipitates are included in the equilibrium constant. asked by eliz on February 25, 2009; Chem What is the value of Kc for the following equation 1/2CH4(g)+H2S(g)goes to 1/2 CS2(g)+ 2H2(g). Which of the following statements describes the behavior of the system if the partial pressure of hydrogen is doubled? which makes you more jittery coffee or tea? at 900 C is 27.8. what is the value of kc for the following equation? is this rxn at equilibrium? (T = 298.17 K) What is G° for this reaction in J/mol? Still have questions? The chief was seen coughing and not wearing a mask. At 25°C, the value of K is 1.7 × 10-13 for the following reaction: . A. CH4 + O → H2O + CO2 B. CH4 + 4O → 2H2O + CO2 C. CH4 + O2 → H2O + CO2 D. CH4 + 2O2 →, Which reaction shows that the enthalpy of formation of CS2 is Hf = 89.4 kJ/mol? Get your answers by asking now. What direction will the reaction proceed, toward reactants or products, to reach equilibrium? a) A decrease in temperature? Supposed you stoppered the flasks after your titration to determine the equilibrium constant and kept the solutions for another day so that the equilibrium was re-established. The Keq or Kc is an same because the made up of the products raised to the potential of their coefficient, divided with the help of the made up of the reactants raised to the potential of their coefficients. a. 4. more H2(g) is produced. the only thing i . Consider the reaction 3Fe(s) + 4H2O(g) ¨ 4H2(g) + Fe3O4(s). The 1st reaction is doubled so the original equilibrium constant is squared. Consider the following reaction: CH4(g) + 2H2S(g) <-> CS2 (g) + 4 H2 (g) A reaction mixtures initially contains 0.50 M CH4 and 0.75 M H2S. Kc=[(1.43M) (1.12M)^4] / [(1.26 M) (1.32)^2]=1.0249. 2. no change occurs. CS2 + 4H2 <--> CH4 +2H2S I'm trying to find a legitimate answer to the question.
