One mole of oxygen at 273 K and one mole of sulphur di-oxide at 546 K are taken in two separate containers, then
Kinetic energy of {{\rm{O}}_2} > {\rm{kinetic\;energy\;of}}\,\;{\rm{S}}{{\rm{O}}_2}
Kinetic energy of {{\rm{O}}_2} < {\rm{kinetic\;energy\;of}}\,\;{\rm{S}}{{\rm{O}}_2}
Kinetic energy of both are equal
None of the above
