Suppose a 250. mL flask is filled with 0.50 mol of Br2, 0.70 mol of OCl2 and 1.4 mol of BrCl.
The following reaction becomes possible: Br2 g +OCl2 g --> <--BrOCl g +BrCl g
The equilibrium constant K for this reaction is 2.39 at the temperature of the flask.
Calculate the equilibrium molarity of OCl2. Round your answer to two decimal places.
The balanced equation for the reaction of bromate ion with bromide in acidic solution is given by: BrO3- + 5Br- + 6H+ -> 3Br2 + 3H2O At a particular instant in time, the value of is 2.0 x 10 -2 mol/L s. What is the value of in same units
