A binary liquid solution is prepared by mixing n - heptane and ethanol. Which one of the following statement is correct regarding the behaviour of the solution?
On a humid day in summer, the mole fraction of gaseous H2O (water vapour ) in the air at 25° C can be as high as 0.0287. Assuming the total pressure of 0.977 atm, what is the partial pressure of dry air ?
Sulphur trioxide can be obtained by which of the following reaction.
The critical temperature of {tex}O_2, N_2, H_2{/tex} and {tex}CO_2{/tex} are 154.3K, 126K, 33.2K and 304K respectively. The extent of adsorption on tungsten may be highest in case of
Fear or exitement, generally cause one to breath rapidly and it results in the decrease of {tex}CO_2{/tex} concentration in blood. In what way will it change the pH of blood?
The rate of a First order reaction 0.04 {tex}mol^{-1} S^{-1}{/tex} at 10 seconds 0.03 {tex}mol^{-1} s^{-1}{/tex} at 20 seconds after intiation of reaction. The half life period of the reaction is
The rate of a reaction doubles when its temperature changes from 300 K to 310 K. Activation energy of such a reaction will be: (R = 8.314 J{tex}K^{-1} mol^{-1}{/tex} and log2 = 0.301)
