either first post or second which ever is easier i need both K AND RATE please

The following initial rate data are for the reaction of UO2+with hydrogen ion in aqueous solution: 2UO2++4H+U4++UO22++2H2O Complete the rate law for this reaction in the box below. Use the form k[A]m[B]n, where ' 1 ' is understood for m or n and concentrations taken to the zero power do not appear. Don't enter 1. for m or n. Rate=k=M2+B1 The following initial rate data are for the reaction of nitrogen dioxide with fluorine: 2NO2+F2+2NO2F Complete the rate law for this reaction in the box below. Use the form k[A]m[B]n, where ' 1 ' is understood for m or n and concentrations taken to the zero power do not appear. Don't enter ? for m or n. Rate=k=M1B1
