The correct plot of the Maxwell-Boltzmann distribution at different temperatures $(T)$ is:

One mole of oxygen at $273 \ K$ and one mole of sulphur dioxide at $546 \ K$ are taken in two separate containers,then:

The total kinetic energy of $0.40 \ mol$ of $Ar$ at $400 \ K$ is equal to the total kinetic energy of $0.30 \ mol$ of $He$ at a temperature of .......... $K$.
