1.a)concentrated sulphuric acid reacts with ethanol to produce ethene

Murljashka [212]

Answer: a) Temperature of $170^0C$

b) $C_2H_5OH\stackrel{conc H_2SO_4, 170^0C}\rightarrow C_2H_4+H_2O$

c) dehydrating agent

Explanation:

Ethanol is heated with an excess of concentrated sulfuric acid at a temperature of 170°C to produce ethene.

The balanced chemical reaction is:

$C_2H_5OH\stackrel{conc H_2SO_4, 170^0C}\rightarrow C_2H_4+H_2O$

Here concentrated sulfuric acid removes a water molecule from ethanol and thus acts as a dehydrating agent.
