If the temperature of an ideal gas is reduced from 600 K to 300 K, wha will be the change in the r.m.s velocity of the gas?

The temperature of an ideal gas is increased from 140 K to 560 K.If at 140 K the root mean square velocity of the gas molecules is V, at 560 K it becomes:

The temperature of a sample of gas is raised from 127^@C to 527^@C . The average kinetic energy of the gas :

What is the meaning of r.m.s speed of a gas molecule ?

Which gas possesses the maximum r.m.s. velocity ?

Write the dependence of r.m.s velocity of a gas on its pressure

State and explain the equation of state for an ideal gas. Why real gases deviate from the ideal behaviour ? What is van der Waal's modification of the gas equations ?

The rate of a reaction becomes four times when the temperature changes from 293 K to 313 K. Calculate the energy of the activation (E_a) of the reaction assuming that it does not change with temperature. [R=8.314" JK"^(-1)" mol"^(-1), log 4 = 0.6021]
