Hi could anyone advise me to weather I am right in thinking when using equation one to calculate the thermal conductivity that C(adsbygoogle = window.adsbygoogle || []).push({}); _{v}is the molar heat capacity and is calculated by use of eqation two for an ideal gas such as argon?

k=n*<v>*mfp*c_{v}/ 3*N_{A}

C_{v,m}= (3/2) * R

Any hints would be much appreciated as the using the above equations i am getting a result which is about 30% out for the expected value of 1.71e-2 J/W/K for the thermal conductivity of argon at s.t.p

Thanks again in advance
