Question

** Please Show & Explain Steps for Solution, so that I can learn the correct way to solve these. **

Part A Consider the following reaction where Kp-10.5 at 350 K. 2CH2CI2(g) CH4(g) CCI4(g) If the three gases are mixed in a rigid container at 350 K so that the partial pressure of each gas is initially one atm, what will happen? 1. A reaction will occur in which CH2C2(g) is consumed. 2. K, will decrease 3. A reaction will occur in which CH4 is produced 4. Qp is less than Kp 5. The reaction is at equilibrium. No further reaction will occur Consider the following reaction where Kc-34.5 at 1150 K: 2SO2(g) + 02(g)2s03(g) A reaction mixture was found to contain 4.34x102 moles of SO2(g), 3.79x102 moles of Part B 02(g) and 3.78x102 moles of SO3(g), in a 1.00 Liter container 1.In order to reach equilibrium SO3(g) must be produced 2. In order to reach equilibrium Kc must decrease. 3. In order to reach equilibrium SO2 must be consumed. 4. Qc is greater than Kc 5. The reaction is at equilibrium. No further reaction will occur. Part C Consider the following reaction where Kc 1.20x102 at 500 K: PCl5 (g)PCl3 (g)+Cl2 (g) A reaction mixture was found to contain 0.110 moles of PC15 (g), 4.54×10-2 moles of PC, (g), and 4.04x10* moles of Cl2 (g), in a 1.00 liter container. 1. In order to reach equilibrium PCI(g) must be produced 3. In order to reach equilibrium PCl3 must be produced 5. The reaction is at equilibrium. No further reaction will occur. 2. In order to reach equilibrium Kc must inc 4. Qc is greater than Kc.

Explanation / Answer

Ans A

Let A = CH2Cl2

B = CH4

C = CCl4

2A = B + C

PA = PB = PC = 1 atm

Reaction quotient Qp = PB x PC / PA2 = 1*1/12 = 1

Qp (1) < Kp (10.5)

Statement 4 is true.

(At equilibrium Qp = Kp) statement 5 is false.

There are more reactants than products

Equilibrium shift in the forward (right) direction (towards product)

Statement 1 is true (reactants will consume)

Statement 3 is true (products will produce)

Kp will increase

Statement 2 is false
