Concept Introduction:
Mass percent can be defined as ratio of calculated mass to the total mass of the compound whole multiplied by
100. The mass percent of compound is given by,
Masspercent(100)=CalculatedMassTotalmass×100
Molality of a solution also called as molal concentration can be defined as the mass of solute in grams to the mass of the solvent in kilograms. It can be given by the equation,
Mole fraction of a compound can be defined as the number of moles of a substance to the total number of moles present in them. The mole fraction can be calculated by,
The reaction is carried out with gases: A → B + C at 300 K. The
total pressure is measured as a function of time (table). If the
reaction order is 2, calculate the rate or kinetic constant k (in
mol-1 L s¹)
