Stoichiometry A gas at 0°C was subjected to constant pressure cooling until its volume became half the original volume. The temperature of the gas at this stage will be -136.5°C -136.5°K 0°C 0°K -136.5°C -136.5°K 0°C 0°K ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry At a constant volume, for a fixed number of moles of a gas, the pressure of the gas increases with rise of temperature due to Increase in average molecular speed Decrease in mean free path Increased collision rate among molecules Increase in molecular attraction Increase in average molecular speed Decrease in mean free path Increased collision rate among molecules Increase in molecular attraction 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 Nearly equal to 4.69 atm Indeterminate due to lack of data Significantly more than 4.69 atm Significantly less than 4.69 atm Nearly equal to 4.69 atm Indeterminate due to lack of data Significantly more than 4.69 atm Significantly less than 4.69 atm ANSWER DOWNLOAD EXAMIANS APP
