Shown below are adsorption isotherms for a gas 'X' at temperatures T1 , T2 and T3 :
         
p and \(\frac xm\) represent pressure and extent of adsorption, respectively. The correct order of temperatures for the given adsorption is:
1.  T1 > T2 > T3
2.  T3 > T2 > T1
3.  T1 = T2 = T3
4.  T1 = T2 > T3

According to the adsorption theory of catalysis, the speed of the reaction increase because:

1. The concentration of reactant molecules at the active centers of the catalyst becomes high due to adsorption
2. In the process of adsorption, the activation energy of the molecules becomes large
3. Adsorption produces heat which increases the speed of the reaction
4. Adsorption lowers the activation energy of the reaction
