L>UntitledProblem Set II1. Write an equilibrium consistent expression, Kc, foreach of the complying with reversible reactions.(a) carbon monoxide gas reduces nitrogen monoxide gregarding gaseousnitrogen; carbon dioxide is the various other product.(b) oxygen gas oxidizes gaseous ammonia to gaseous nitrogen monoxide;water vapor is the various other product.(c) solid sodium hydrogen carbonate decomposes to create solid sodiumcarbonate, water vapor, and carbon dioxide gas.Exsimple why we typically exclude pure solids and pure liquids fromthe equilibrium expression.This question needs some abilities which you have to havelearned in the previous semester: Translating sentences intobalanced muzic-ivan.infoical equations. (a) carbon monoxide gas = CO(g)nitrogen monoxide gas = NO(g)gaseous nitrogen = N2(g)carbon dioxide gas = CO2(g)Due to the fact that the equilibrium expression entails concentrationterms, it is incredibly crucial to specify the phase of each of thereactants and also the products.Unwell balanced muzic-ivan.infoical Equation:CO(g) + NO(g) N2(g) + CO2(g)Balanced muzic-ivan.infoical Equation:CO(g) + NO(g) (1/2)N2(g) +CO2(g)Equilibrium Expression:or;Balanced muzic-ivan.infoical Equation:2CO(g) + 2NO(g) N2(g) + 2CO2(g)Corresponding Equilibrium Expression:The equilibrium expression depends on exactly how the balanced equationis created. Both Kc and Kc" are constants. Kc", in truth, is equal to Kc2.(b)Unbalanced muzic-ivan.infoical Equation:O2(g) + NH3(g) NO(g)+ H2O(g)Balanced muzic-ivan.infoical Equation:5O2(g) + 4NH3(g) 4NO(g) + 6H2O(g)Corresponding Equilibrium Expression:(c)Unbalanced muzic-ivan.infoical Equation:NaHCO3(s) Na2CO3(s)+ H2O(g) + CO2(g)Balanced muzic-ivan.infoical Equation:2NaHCO3(s) Na2CO3(s)+ H2O(g) + CO2(g)Corresponding Equilibrium Expression:Pure solids or liquids are excluded from the equilibriumexpression bereason their reliable concentrations continue to be constantthroughout the reactivity. The concentration of a pure liquid orsolid equals its thickness split by its molar mass. The densityof a pure liquid or solid is the very same, regardmuch less of just how muchpure liquid or solid is current.Only the concentrations of gases and also substances in solutionare included in the equilibrium expression.2. Suppose that the reactions A--> B and B--> A are bothelementary processes via rate constants of 9.62 x 102s-1 and 3.8 x 104 s-1, respectively.(a) What is the value of the equilibrium continuous for the equilibriumA B?(b) Which is greater at equilibrium, the concentration of A orthe concentration of B? Exordinary.If a reversible reactivity is composed of 2 opposing elementaryprocesses, the equilibrium continuous is equal to the proportion of theforward price consistent to the reverse price constant:(a) Kc = (9.62 x 102)/(3.8 x 104)= 0.025(b) Because Kc = / and also Kc > 3. In the reaction 2HI(g) H2(g) + I2(g)at 623 K, starting with 0.315 g HI in a 0.400-L bulb, the massof I2(g) uncovered at equilibrium is 0.0615 g. What isthe value of Kc for this reaction?This trouble combines the concept of muzic-ivan.infoical equilibrium,stoichiomeattempt and the Law of Conservation of Mass.The reactivity started via 0.315 g HI, no I2 and also noH2. Hence, at any time duration, the complete mass has actually toreprimary consistent, 0.315 g.At equilibrium, 0.0615 g of I2 is existing. Applyingstoichiomeattempt to this problem, one arrives at the adhering to relationships. The just source of both I2 and H2 is HIgiven that there was no I2 and H2 initially current. This indicates that the number of moles of I2 presentneed to equal the number of moles of H2 existing andthe staying number of moles of HI need to equal the initial amountminus twice the variety of moles of I2 present:At equilibrium:n I2 = n H2n HI = (initial n HI) - 2 n I2Kc =
