Would anyone care to check if this is correct? (Equilibrium) - Homework Help - Science Forums
Would anyone care to check if this is correct? (Equilibrium) - posted in Homework Help: Id appreciate any help, as I am aware that these kinds of problems are only slightly tedious. Thank you in advance! My answer seems a tad low for a Kc value, which is why I am asking on here. A mixture of 0.546 mole of carbon monoxide and 0.407 mole of bromine was placed into a rigid 1.21-L container (i.e. these are initial amounts) and the system was allowed to come to equilibrium. The equilibrium conc...

~chemistry space~: Summary On Equilibrium Constants 2
KcDefinition: Equilibrium constant is a measure of the ratio of concentrations of products and reactants at equilibrium. What the value of K measures: equilibrium concentrationType of system K applies to: molarity, system at equilibriumExample of an equation (include state symbols): CO(g)+Br2(g) CoBr2(g)Expression for K: Kc=[CoBr2]/[CO][Br2]Unit:mol dmˉ³KpDefinition: For reactions involving gases, the equilibrium constant of a gaseous reaction can also be expressed in terms of partial pressure.
