I need help answering questions 2 and 3 please. picture attachedChemical KineticsIf a chemical reaction is first order , and a kinetics experiment is performed in which theconcentration of the reactant is followed as a function of time what will the units of the rateconstant be if concentration is expressed in units of Molarity and time is measured in units ofminutes ?!K = min – 12 .A certain first order chemical reaction is 50% complete in 140 seconds . Calculate the rateconstant of the reaction ."NOTE : be sure to report units with your answer .3.The phenolphthalein / hy droxide reaction that you will study today is typical of most chemicalreactions in its response to temperature . Will it , therefore , be slower or faster at 5 Cincomparison to its rate at room temperature ?"
