Chapter 12, Problem 70QRT

(a)

Interpretation Introduction

Interpretation:

For the given reaction, the affect of equilibrium on addition of more of Br2 has to be given.

Concept Introduction:

Le Chatelier's principle:

It states that if a system in equilibrium gets disturbed due to modification of concentration, temperature, volume, and pressure, then it reset to counteract the effect of disturbance.

Endothermic reaction:

For an endothermic reaction, an increase in temperature results in an increase in Kc.  At higher temperatures, endothermic reactions are more product favoured.

(b)

Interpretation Introduction

Interpretation:

For the given reaction, the affect of equilibrium on removal of some of NOBr has to be given.

Concept Introduction:

Refer part (a)

(c)

Interpretation Introduction

Interpretation:

For the given reaction, the affect of equilibrium on lowering the temperature has to be given.

For the reaction, 2SO2(g) + O2(g) ⇌ 2SO3(g), ∆H = -57.2 kJ mol–1 and Kc = 1.7 × 1016 Which of the following statements is incorrect? (a) The equilibrium will shift in the forward direction as the pressure increases. (b) The addition of inert gas at constant volume will not affect the equilibrium constant. (c) The equilibrium constant is large, suggestive of reaction going to completion and so no catalyst is required. (d) The equilibrium constant decreases as the temperature increases.
The equilibrium constant for the “water gas” reaction: C(s)+H2O(g) <--> CO(g)+H2(g)             k=2.6at a temperature of 1000 K. Calculate the reaction quotient Q for each of the following conditions, and state which direction the reaction shifts in coming to equilibrium.(a) P(H2O) = 0.6 atm ; P(CO) = 1.525 atm ; P(H2) =0.805 atm(b) what is the pressure of each gas when the reaction reach equilibrium. Carbon is enoughto react
The following reaction has an equilibrium constant, Kc, of 2.10 x 102 at a particular temperature: N2 (g) + 3 H2 (g) → 2 NH3 (g) +You have a container in which the concentration of N2 is 0.77 M, the the concentration of H2 is 0.84 M, andthe concentration of NH3 is 0.85 M.(a) Calculate the value of the reaction quotient Q.(b) Is the system at equilibrium? If not, predict which way (right or left) the reaction will proceed toreach equilibrium.
