The conductivity of 0.02 M of KCl solution at 298 K is 0.0123 $\text{ohm}^{-1}\ \text{cm}^{-1}$. If the resistance of the cell containing this solution is 120 ohms, what is the value of the cell constant ?

Half life of zero order reaction is 1 hour. If initial concentration of reactant is 2.0 mol $\text{L}^{-1}$, find the time required to decrease concentration from 0.50 to 0.25 mol $\text{L}^{-1}$

What is the term used for the minimum kinetic energy required for the reactant molecules to undergo reaction?

If time required for 90 % completion of a first order reaction is '$t$'. What is the time required for 99.9 % completion of reaction at same temperature?
