(b)
(c)
Answer:
(a) Nickel (Ni) acts as
the catalyst during the reaction. It first adsorbs the hydrogen molecule on its
surface as hydrogen atoms and then the alkene molecule side by side.
The two hydrogen
atoms then add across the double bond of the alkene to form the addition
product i.e., 2, 3- dimethyl butane.
(b) Cone. 
increases
the rate of the forward reaction by removing 
formed
during the reaction. In other words, cone acts
as a dehydrating agent.
(c) Alkaline
acts
as an oxidizing agent and oxidizes ethanol to ethanoic acid.
