If you wanted to make a 3 liter solution of 500 mM formic acid buffer at pH 3.9 how many grams each of sodium formate (MW=68g/mol) and formic acid (MW=46g/mol) would you add
The value of Kc for this reaction is 5.0 at 600 K. What are the equillibrum partial pressures of the three gases if a reaction vassel initially contains a mixture of the reactants in which Pco=Pcl2=0.215 atm and Pcocl2= 0.000 atm?
[BrO- ]initial is 0.86 M. 65 seconds later [BrO- ] is 0.19 M. What is the rate of change of [BrO- ] in M/s? (The brackets, [ ], indicate concentration, that is, molarity (M) or moles/liter.)
