The reaction H₂(g) + 12(g) ⇒ 2HI(g) has AG° = +3.3 kJ mol-¹ at 25.0 °C. What is the value of Kp at this temperature? Kp = دے

At 13.7 °C the concentration equilibrium constant K = 2.0 × 10 for a certain reaction. Here are some facts about the reaction: • C The constant pressure molar heat capacity C₁ = 2.49 J-mol K. •If the reaction is run at constant pressure, 147. kJ/mol of heat are released. •If the reaction is run at constant pressure, the volume increases by 13.%. ○ Yes. Using these facts, can you calculate K, at 3.8 °C? x10 No. If you said yes, then enter your answer at right. Round it to 2 significant digits. n If you said no, can you at least decide whether Kat 3.8 °C will be bigger or smaller than K at -13.7 °C? Yes, and K will be bigger. Yes, and K will be smaller. No. x

Phosgene (COCl2) is used in the manufacture of foam rubber and bulletproof glass. It is formed from carbon monoxide and chlorine in the following reaction:Cl2​(g)+CO(g) ----> COCl2​(g)   The value of Kc for the reaction is 17.1 at 540.4 °C. What is the value of Kp at 540.4 °C?

If the KP for the reaction CO(g) + H2O(g) ⇌ CO2(g) + H2(g) was calculated to be 3.32 × 103 at 298.15 K, at what temperature does KP = 5.00 × 103? What is the highest value that KP can have by changing the temperature? Assume that ΔHo is independent of temperature and that 1/∞ = 0.

Calculate the value of K, for the equation C(s) + CO₂(g) given that at a certain temperature Kp = 2 CO(g) K₂ = ? C(s) + 2 H₂O(g) CO₂(g) + 2 H₂(g) H₂(g) + CO₂(g) = H₂O(g) + CO(g) Kpl = 3.35 Kp2 = 0.745

Kp for the following reaction is 0.16 at 25 0C. 2NOBr(g)=2NO (g)+ Br2 (l) the enthalpy change for the reaction at standard conditions is +16.1 kJ. State which way the equilibrium will shift (left, right or no change) when each of the following changes is made. Breifly explain credit for result. (a) adding more Br2 (l) (b) removing some NOBr (g) (c) Decreasing the temperature (d) increasing the container volume (e) increasing the total pressure by adding an inert gas.

Consider the following equilibrium: 2NOC1 (g) → 2NO(g) + Cl₂ (g) AG = 41. kJ Now suppose a reaction vessel is filled with 8.30 atm of nitrosyl chloride (NOC1) and 5.80 atm of chlorine (C1₂) at 878. °C. Answer the following questions about this system: Under these conditions, will the pressure of Cl₂ tend to rise or fall? Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of Cl₂ will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of Cl₂ will tend to fall, can that be changed to a tendency to rise by adding NO? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it. Round your answer to 2 significant digits. оо rise fall yes no 0 atm x10 X Ś

For the following reaction: NH4Cl(s) ↔ NH3(g) + HCl(g) ΔH = +42.1 kilocalories Suppose the substances in the reaction above are at equilibrium at 600K in volume V and at pressure P. State whether the partial pressure of NH3(g) will have increased, decreased, or remained the same when equilibrium is reestablished after each of the following disturbances of the original system. Some solid NH4Cl remains in the flask at all times. Justify each answer with a one-or-two sentence explanation. (e) A quantity of gaseous NH3 is added. The answer for e states that the partial pressure of NH3 is increase, which is a bit confusing. The explanation is that some of the the added NH3 reacts with HCl to relieve stress but only part of NH3 reacts. Can you explain how and where this is implied in the reaction or question. Would appreciate a lot of clarification
