Question

what is the average kinetic energy of a gas at 285 kelvin (r = 8.314 j/k-mol)

Answer 1

as we know that average kinetic of a gas is given by the equation
K.E=3(K)(T)/2
where value of k=1.3*10^-23
by putting the value of temperature you can find avg k.e

Answer 2

so what is the answer then? 3.55 x 103 J/mol??
