Explanation Given The stated reaction is, C 2 H 5 OH ( l ) + 3 O 2 ( g ) → 2 CO 2 ( g ) + 3 H 2 O ( l ) The standard enthalpy of formation of one mole of CO 2 is − 393.5 kJ . The standard enthalpy of formation of one mole of H 2 O is − 285.83 kJ . The standard enthalpy of formation of one mole of C 2 H 5 OH is − 277.7 kJ . The standard enthalpy of formation of one mole of O 2 is 0 kJ . The enthalpy change of the reaction is calculated by the formula,] Δ H r e a c t i o n ° = ∑ n Δ H f ° ( products ) − ∑ m Δ H f ° ( reactancts ) = [ 2 Δ H f ° ( CO 2 ) + 3 Δ H f ° ( H 2 O ) ] − [ Δ H f ° ( C 2 H 5 OH ) + 3 Δ H f ° ( O 2 ) ] Where, Δ H r e a c t i o n ° is the enthalpy change of the reaction

Ideal and Real Gases

Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,

Gas Laws

Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries we…
