Question

(a)What is a catalyst ? Write the chemical equation to represent the hydrogenation of ethene. (b) Which of the following compounds belong to the same homologous series ? C2H6 C2H6O2, C2H6O, C4HI0

Answer 1

Answer: A catalyst is a substance that does not takes part in a checmical reaction but increase or decrease the rate of the chemical reaction

Explanation:

Answer 2

Hello Student,

(a) Catalyst -

A catalyst is a substance that speeds up a chemical reaction but is not consumed by the reaction.

Hydrogenation of ethene -

Ethene on hydrogenation gives ethane.

CH2=CH2 + H2 --> CH3-CH3

(b) Homologues -

C2H6 (ethane) and C4H10 (butane) are members of same homologous series alkanes.
