Ethene is formed when ethanol at 443 K is heated with excess of concentrated sulphuric acid. What is the role of sulphuric acid in this reaction? Write the balanced chemical equation of this reaction.

AcademicChemistryNCERTClass 10

Concentrated sulphuric acid removes water from ethanol, hence, acts as a dehydrating agent. 
The balanced chemical equation for the reaction can be written as:
$CH_3CH_2OH \xrightarrow [443K] {conc.H_2SO_4} CH_2=CH_2 +  H_2O$
