The average speed at `T_1` K and the most probable speed at `T_2` K of `CO_2` gas is `9xx10^4cmsec^(-1)`. Calculate the value of `T_1` and `T_2`.

The average velocity of the molecules of a gas at T_(1)K will be the same as the most probable velocity of the molecules of the gas at T_(2)K when-

Activation energy ( E_a ) and rate constants ( k_1 and k_2 ) of a chemical reaction at two different temperature ( T_1 and T_2 ) are related by

The temperature of a fixed mass of an ideal gas is changed from T_(1)K to T_(2)K(T_(2) > T_(1)) . Calculate the work done if the change is brought about at (i) constant pressure (ii) constant volume. Hence find from the first law of thermodynamics, in which case heat absorbed will be greater.

The density of gas A is d_(A) at a temperature of T_(A)K , and the density of gas B is d_(B) at a temperature of T_(B)K . The molar mass of A is 4 times that of B. if T_(A):T_(B)=2:1 and d_(A),d_(B)=1:2 , the ratio of pressure of A to B is-

At T K, what will be the value of (H-U) for 1 mol of ideal gas?

Pressure (P) vs. density (D) curve for an ideal gas at two different temperatures T_1 and T_2 is shown below . Identify the correct statement about T_1 and T_2 .

The decomposition of hydrocarbon follows the equation k =(4.5xx10^(11)s^(-1))e^(-28000K//T) . Calculate E_(a) .
