The following equation was performed at 551 oC 3Y(s) + X(g) ⇌ M(g) + 2Z(g) The Kp of the reaction is 0.00773. Calculate the Kc at the same temperature (R = 0.0821 atm.L/K/mol)

The value of Kp for the reaction 2 A(g) + B(g) + 3 C(g) -> 2 D(g ) + E(g) is 18650 at a particular temperature. Which of the following is the correct expression for Kp?

At 1130ºC the equilibrium constant (Kc) for the reaction 2H2S(g)  ⇌  2H2(g)  +  S2(g) is 2.25 × 10–4. If [H2S] = 4.84 × 10–3 M and [H2] = 1.50 × 10–3 M, calculate [S2].

For the following reaction, H2(g) + I2(g) ⇌ 2 HI(g), Kp = 44 at 25.0 o C. Calculate the value of Kc

The reaction mixture below contains 0.305 atm of H2, 0.060 atm of S2, and 0.420 atm of H2S. 2 H2S(g) 2 2 H2(g) + S2(g) Kp = 2.4x104 at a particular temperature. Based on the information provided, select the correct relationship. K; the reaction will proceed to form more S2(g). Q > K; the reaction will proceed to the left. O More experimental data are needed to answer a question of this type. Q = K; the reaction is at equilibrium and no change is expected.

Nitrogen dioxide reacts to form dinitrogen tetroxide as follows: 2 NO2 N₂04 (g) At 150 °C, Kp = 4.51. If one starts with 10.0 atm NO2 (g), what is the equilibrium pressure (in atm) of N₂O4 (g)?

At 487 K, this reaction has a Ke value of 0.0463. 2 X(g) + 3 Y(g) = 2Z(g) Calculate Kp at 487 K. Note that the pressure is in units of atmosphere (atm). Kp =

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
