Question

S. The reaction af SulFuric aid with sodium car borate In aqueous Solution represented bythe follousing equation Ha SO4 (og) Nag COs (ag)-7 NhaSOu (oa)t H0 (a)t COarg Assume tha the reaction s carried thermodynamic conditions Compute the amaunt volume, w0rk that is done by the system out at under Standard of Pressure, on the surround ings of SuIforic acid reacts with ohen ane mole Cre mole c sodium carbonate.

Answer 1

5) When one mole of sulfuric acid reacts with a mole of sodium carbonate, one mole of CO₂ is liberated.

It is an irreversible process, the reaction being exothermic, the gas expands.

The expansion work done during an isothermal irreversible process is,

w= -pdeltaV= -1.103x10⁵ x1L [From Avogadro's law, V is directly proportional to n]

=- 1.103x10⁵Pa x 10^-3m³ = -1.103 x10² Pa m³

= - 110.3J
