An aqueous reaction is taking place in a liter of water that is being stirred in a 5-liter flask? If the entire reaction was transferred to a 2-liter flask, what would be the effect on the overall reaction rate?

Explanation:

Collisoin Theory define the  chemical reaction kinetics and their factor affecting . According to Collision theory of chemical reaction , when reactant molecules collide effectively then reaction took place .

The overall reaction rate are depends mainly on four main factor according to collision theory ;

(1) Temperature

(2) Prsence of catalyst

(3) Reactant Concentration

(4) Surface Area

Here , Overall reaction rate increasing upon increasing surface area and vice - versa . Since , surface area is directly proportional to volume and here volume is decreased from 5 lit - 2Lit  . hence , overall reaction rate is also decreased .  

the answer for sodium is 0.186

the answer for rubidium is 0.251
