Spontaneity

The average translational KE =

%5Cfrac%7B3%7D%7B2%7DkT

which is directly proportional to T, while rms speed of molecules is given by

When temperature of gas is increased from 300 K to 600 K
(i.e. 2 times), the average translational KE will increase to \2 times and rms speed to

%5Csqrt%202

or 1.414 times.
