Decide whether each of the following statements is true or false.  If false, change the wording of the statement to make it true.   a) The magnitude of the equilibrium constant is always independent of temperature. b) When two chemical equations are added to give a net equation, the equilibrium constant for the net equation is the product of the equilibrium constants of the summed equations. c) The equilibrium constant for a reaction has the same value as K for the reverse reaction.  d) Only the concentration of CO2 appears in the equilibrium expression for the reaction: CaCO3 (s) ↔ CaO (s) + CO2 (g). e) For the reaction CaCO3 (s) ↔ CaO (s) + CO2 (g), the value of K is numerically the same whether the amount of CO2 is expressed as molarity or as gas pressure.

the equilibrium constant (K) is a quantitative measurement of theextent to which a chemical or physical reaction proceeds to completion. If two reactants ofknown initial concentration are mixed and then the concentrations of the products aremeasured once equilibrium has been established, then the equilibrium constant can becalculated using an ICE table.In this experiment you will measure the equilibrium constant for the formation of iron(III)thiocyanate from the iron(III) cation and thiocyanate anion:Fe3+(aq) + SCN-(aq) FeSCN2+(aq)The product, FeSCN2+, is intensely red, which means that its concentration can be measured byusing an ultraviolet-visible (UV-vis) spectrophotometer.

"Synthesis gas" is a mixture of carbon monoxide and water vapor. At high temperature synthesis gas will form carbon dioxide and hydrogen, and in fact this reaction is one of the ways hydrogen is made industrially. A chemical engineer studying this reaction fills a 200. mL flask with 3.6 atm of carbon monoxide gas and 2.5 atm of water vapor. When the mixture has come t equilibrium she determines that it contains 2.0 atm of carbon monoxide gas, 0.90 atm of water vapor and 1.6 atm of carbon dioxide. The engineer then adds another 1.2 atm of carbon monoxide, and allows the mixture to come to equilibrium again. Calculate the pressure of hydrogen after equilibrium is reached the second time. Round your answer to 2 significant digits. atm x10
