Stoichiometry What is the total pressure exerted by a mixture of 0.45 kg mole of benzene, 0.44 kg mole of toluene and 0.23 kg mole of o-xylene at 100°C, if their vapor pressures at 100°C are 1340, 560 and 210 mmHg respectively? 780.5 880.5 801.5 756.2 780.5 880.5 801.5 756.2 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry An ideal gas can be liquified, because Its critical temperature is more than 0°C It gets solidified directly without becoming liquid Forces operative between its molecules are negligible Its molecular size is very small Its critical temperature is more than 0°C It gets solidified directly without becoming liquid Forces operative between its molecules are negligible Its molecular size is very small ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry No cooling occurs, when an ideal gas undergoes unrestrained expansion, because the molecules Collide without loss of energy Exert no attractive force on each other Are above the inversion temperature Do work equal to loss in kinetic energy Collide without loss of energy Exert no attractive force on each other Are above the inversion temperature Do work equal to loss in kinetic energy ANSWER DOWNLOAD EXAMIANS APP
