1. The ideal gas law relates the measurable quantities P, V, and T of a perfect gas at low pressures, and its expression is given by: PV = nRT (a) Name all Sl Base physical quantities that are linked to the expression above and show how you have Identified them. (4) (b) Show how to find the SI unit of gas constant PV = nRT N.B all units must be in Sl. 2. If the hydrolysis rate constant of a chemical reaction increases with the increase of temperature, then their relationship could be expressed as: Ink = + InA Where k is the first-order coefficient (s¹) is time A is the pre-exponential factor, Ea(J mol-¹') is the reaction activation energy,T(K) is the absolute temperature and R is the gas constant. (a) Name all Sl Base physical quantities that are linked to the expression above. (4) (b) Show the unit of measure of pre-exponential factor A is the same as the unit of measure of k. (5)
