For a neutral solution (pH = 7), the value of[H⁺] [OH⁻] is equal to < 1 1 > 1 TRUE ANSWER : ? YOUR ANSWER : ?
Gases diffuse faster compared to liquids because of the reason that the liquid molecules Have no definite shape Are heavier Move faster Are held together by stronger inter-molecular forces TRUE ANSWER : ? YOUR ANSWER : ?
At room temperature, the product [H⁺] [OH⁻] in a solution is 10⁻¹⁴ moles/litre. If, [OH⁻] = 10⁻⁶ moles/litre, then the pH of the solution will be 6 8 10 12 TRUE ANSWER : ? YOUR ANSWER : ?
Kopp's rule is helpful in finding the Heat capacities of solids Heat capacities of gases Molal heat capacities of gases Activation energy TRUE ANSWER : ? YOUR ANSWER : ?
For estimation of heat capacity of a solid compound, one can use Trouton's rule Gibb's equation Kopp's rule Clayperon's equation TRUE ANSWER : ? YOUR ANSWER : ?
Unrestrained expansion of an ideal gas does not result in its cooling due to the reason that the gas molecules Do work equal to loss in kinetic energy Are above the inversion temperature Do not exert attractive force on each other Do not lose energy on collision TRUE ANSWER : ? YOUR ANSWER : ?
'Cox' chart which is useful in the design of a distillation column (particularly suitable for petroleum hydrocarbons) is a plot of the Temperature vs. log (vapor pressure) Vapor pressure vs. log (temperature) Vapor pressure vs. temperature Log (temperature) vs. log (vapor pressure) TRUE ANSWER : ? YOUR ANSWER : ?
The heat capacity of a solid compound is approximately equal to the sum of the heat capacities of the constituent elements. This is the statement of Nearnst heat theorem Law of Petit and Dulong Kopp's rule Trouton's rule TRUE ANSWER : ? YOUR ANSWER : ?
In case of a solution (not of a solid in a liquid), whose total volume is more than the sum of volumes of its components in their pure states, solubility is Increased with the increase in pressure Decreased with the increase in pressure Unchanged by the pressure change Independent of the temperature TRUE ANSWER : ? YOUR ANSWER : ?
