Stoichiometry In case of a solution (not of a solid in a liquid), whose total volume is less than the sum of the volumes of its components in their pure states, solubility is Increased with decrease in pressure Unchanged with pressure changes Independent of temperature Increases with rise in pressure Increased with decrease in pressure Unchanged with pressure changes Independent of temperature Increases with rise in pressure ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry At 100°C, water and methylcyclohexane both have vapour pressures of 1 atm. Also at 100°C, the latent heats of vaporisation of these compounds are 40.63 kJ/mole for water and 31.55 kJ/mole for methylcyclohexane. The vapour pressure of water at 150°C is 4.69 atm. At 150°C, the vapour pressure of methylcyclohexane would be expected to be Significantly less than 4.69 atm Significantly more than 4.69 atm Nearly equal to 4.69 atm Indeterminate due to lack of data Significantly less than 4.69 atm Significantly more than 4.69 atm Nearly equal to 4.69 atm Indeterminate due to lack of data ANSWER DOWNLOAD EXAMIANS APP
