Stoichiometry A perfectly insulated container of volume V is divided into two equal halves by a partition. One side is under vacuum, while the other side has one mole of an ideal gas (with constant heat capacity) at 298 K. If the partition is broken, the final temperature of the gas in the container Can not be determined Will be greater than 298 K Will be less than 298 K Will be 298 K Can not be determined Will be greater than 298 K Will be less than 298 K Will be 298 K ANSWER DOWNLOAD EXAMIANS APP

Stoichiometry According to Raoult's law, "The vapor pressure exerted by component in a solution is proportional to the mole fraction of that component." Raoult's law is not applicable under the following assumption/condition. The component molecules are non polar and are of almost equal size No component is concentrated at the surface of the solution The attractive forces between like and unlike molecules are almost equal In the formation of solution, chemical combination/molecular association between unlike molecules takes place The component molecules are non polar and are of almost equal size No component is concentrated at the surface of the solution The attractive forces between like and unlike molecules are almost equal In the formation of solution, chemical combination/molecular association between unlike molecules takes place ANSWER DOWNLOAD EXAMIANS APP
