SURFACE CHEMISTRY

20812 Which one of the following substances adsorb hydrogen gas most strongly

1 Activated carbon
2 Silica gel
3 Platinum black
4 Iron powder
SURFACE CHEMISTRY

20813 According to the adsorption theory of catalysis, the speed of the reaction increases because

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

20814 In Freundlich adsorption, isotherm adsorption is proportional to pressure \(P\) as

1 \({P^0}\)
2 \(P\)
3 \({P^n}\)
4 \({P^{1/n}}\)
SURFACE CHEMISTRY

20879 A catalyst added to a reaction mixture

1 Increases the equilibrium constant
2 Decreases the equilibrium constant
3 Does not change the equilibrium constant
4 None of these
