Stoichiometry In case of a solution (not of a solid in a liquid), whose total volume is more than the sum of volumes of its components in their pure states, solubility is Decreased with the increase in pressure Independent of the temperature Unchanged by the pressure change Increased with the increase in pressure Decreased with the increase in pressure Independent of the temperature Unchanged by the pressure change Increased with the increase in pressure ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Vapor pressure of a solution is proportional to(where, Sv and St are mole fraction of solvent and solute respectively). St 1/Sv 1/St Sv St 1/Sv 1/St Sv ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry The vapor pressure of the solvent decreased by 10 mm Hg, when a non-volatile solute was added to the solvent. The mole fraction of the solute in the solution is 0.2. What should be the mole fraction of the solvent, if the decrease in vapor pressure of the solvent is required to be 20 mm Hg.? 0.4 0.1 0.6 0.2 0.4 0.1 0.6 0.2 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Heat of neutralisation of a strong acid and strong base is always a constant value, i.e., 57 KJ/Kg mole. This is because The salt formed does not hydrolyse The strong base and strong acid reacts completely Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts in aqueous solution The salt formed does not hydrolyse The strong base and strong acid reacts completely Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts in aqueous solution ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry A butane isomerisation process produces 70 kmole/hr of pure isobutane. A purge stream removed continuously, contains 85% n-butane and 15% impurity (mole%). The feed stream is n-butane containing 1% impurity (mole%). The flow rate of the purge stream will be 3 kmole/hr 6 kmole/hr 4 kmole/hr 5 kmole/hr 3 kmole/hr 6 kmole/hr 4 kmole/hr 5 kmole/hr ANSWER DOWNLOAD EXAMIANS APP
