Interpretation:
Whether the reaction will proceed to the right, the left, or neither to achieve equilibrium for each of the given diagrams is to be determined.
Concept introduction:
For a general reaction:
Reaction quotient is defined as the ratio of concentration of products and reactants of chemical species present in the reaction mixture at a given point of time. It is denoted with
Equilibrium constant is defined as the ratio of concentration of products and the concentration of reactants, which are in equilibrium, and its value is constant at a particular temperature. It denoted by K.
Here,
A and B are reactants, C and D are products, and
At equilibrium,
The equilibrium concentration of reactants and products, present in liquid or solid phase, in the reaction is considered to be

- A sample of gaseous nitrosyl bromide (NOBr) was placed in a container tiued with a frictionless, massless piston, where it decomposed at 25C according to the following equation: 2NOBr(g)2NO(g)+Br2(g) The initial density of the system was recorded as 4.495 g/L. After equilibrium was reached, the density was noted to be 4.086 g/L. a. Determine the value of the equilibrium constant K for the reaction. b. If Ar(g) is added to the system at equilibrium at constant temperature, what will happen to the equilibrium position? What happens to the value of K? Explain each answerarrow_forwardIsopropyl alcohol is the main ingredient in rubbing alcohol. It can decompose into acetone (the main ingredient in nail polish remover) and hydrogen gas according to the following reaction: C3H7OH(g)C2H6CO(g)+H2(g)At 180C, the equilibrium constant for the decomposition is 0.45. If 20.0 mL (d=0.785g/mL) of isopropyl alcohol is placed in a 5.00-L vessel and heated to 180C, what percent- age remains undissociated at equilibrium?arrow_forwardFor the following reactions, predict whether the pressure of the reactants or products increases or remains the same when the volume of the reaction vessel is increased.

- 7-32 A particular reaction has an equilibrium constant of 1.13 under one set of conditions and an equilibrium constant of 1.72 under a different set of conditions. Which conditions would be more advantageous in an industrial process that sought to obtain the maximum amount of products? Explain.arrow_forwardFor a typical equilibrium problem, the value of K and the initial reaction conditions are given for a specific reaction, and you are asked to calculate the equilibrium concentrations. Many of these calculations involve solving a quadratic or cubic equation. What can you do to avoid solving a quadratic or cubic equation and still come up with reasonable equilibrium concentrations?arrow_forwardConsider the decomposition equilibrium for dinitrogen pentoxide: 2N2O5(g)4NO2(g)+O2(g) At a certain temperature and a total pressure of 1.00 atm, the N2O5 is 0.50% decomposed (by moles) at equilibrium. a.
