Question

does same phase and diffrent phase in homogenous and heterogenous catalysts effects the speed of reaction?

Open in App

Solution

Catalyst always used to increase the rate of reaction.
If the phase of catalyst is same as reactant it is homogenous catalysis.
If the phase of reactant is different as catalyst it is heterogeneous catalysis.
If you are talking about phase change then you are converting your reaction from homogenous to heterogeneous catalysis.
But the rate of reaction will be same.

Q. A mixture of sulphur and carbon disulphide is :
(a) heterogeneous and shows Tyndall effect
(b) homogeneous and shows Tyndall effect
(c) heterogeneous and does not show Tyndall effect
(d) homogeneous and does not show Tyndall effect

Q. Assertion :In the reaction,

C_{12} H_{22} O_{11} (a q) + H_{2} O (l) d i l H_{2} S O_{4} ⟶ C_{6} H_{12} O_{6} (a q) + C_{6} H_{12} O_{6} (a q), H_{2} S O_{4}

is called as a homogeneous catalyst. Reason:

H_{2} S O_{4}

is in the same phase as the reactants and products.
