(a)
Interpretation:
A table of initial concentrations, change in concentrations and equilibrium concentrations for the below given reaction has to be given.
Concept Introduction:
ICE table:
The full form of ICE table is Initial Change Equilibrium table. It is used to solve initial concentrations or pressures in equilibrium reactions.
Reaction Quotient:
Reaction quotient, Q is the ratio between product of the product concentration to the product of the reactant concentration with each term raised to the power of its balancing coefficient.
Consider a general equation,
Where a, b, c and d are the
The concentration of solids and pure liquids do not change, so their concentration terms are not included in the reaction quotient expression.
(b)
Interpretation:
The equilibrium constant expression in terms of x has to be written and then the variable ‘x’ has to be solved for the given reaction.
Concept Introduction:
Equilibrium constant: At equilibrium the ratio of products to reactants (each raised to the power corresponding to its stoichiometric coefficient) has a constant value, K
For a general reaction,
The concentration of solids and pure liquids do not change, so their concentration terms are not included in the equilibrium constant expression.
(c)
Interpretation:
The equilibrium concentration of each isomer of the given reaction under given experimental conditions has to be calculated.

- The equilibrium constant Kc for the synthesis of methanol, CH3OH. CO(g)+2H2(g)CH3OH(g) is 4.3 at 250C and 1.8 at 275C. Is this reaction endothermic or exothermic?arrow_forwardHydrogen gas and iodine gas react to form hydrogen iodide. If 0.500 mol H2 and 1.00 mol I2 are placed in a closed 10.0-L vessel, what is the mole fraction of HI in the mixture when equilibrium is reached at 205C? Use data from Appendix C and any reasonable approximations to obtain K.arrow_forwardThe equilibrium constant for the butane iso-butane equilibrium at 25 C is 2.50.

Gaseous phosphorus pentachloride decomposes according to the reaction PCl5(g)PCl3(g)+Cl2(g)The equilibrium system was analyzed at a particular temperature, and the concentrations of the substances present were determined to be [PCl5]=1.1102M,[PCl3]=0.325M. and [Cl2]=3.9103M. Calculate the value of K for the reaction.arrow_forwardNitrosyl chloride, NOC1, decomposes to NO and Cl2 at high temperatures. 2 NOCl(g) ⇌ 2 NO(g) + Cl2(g) Suppose you place 2.00 mol NOC1 in a 1.00–L flask, seal it, and raise the temperature to 462 °C. When equilibrium has been established, 0.66 mol NO is present. Calculate the equilibrium constant Kc for the decomposition reaction from these data.arrow_forward
