So the average amount of kinetic energy in a gas molecule would be equal to three halves, multiplied by cable, spins constant, multiplied by by T the temperature. My apologies for part A. We for an ideal gas, the average kinetic energy per molecule rests upon only the temperature because Holtzmann constant is of course simply a constant. So for part A we can say that the kinetic energy for neon kinetic energy for krypton and the kinetic energy for Rayden would be equal to simply 12121 again, if all of them are at the same temperature. Now, for part B, we want to find the root, mean squared root, mean squared velocity, or speed of a molecule. This would be the square root, or rather Equalling square root of three times the ideal gas constant times the temperature divided by the molar mass of the gas. And so for we can calculate this for neon root mean square speed for neon Would be equal to the square root of three times 8.3145. This would be jewels per mole Calvin multiplied by the temperature here. And we could just simply keep this as T divided by the Mueller mass At 20.18 we can say kilograms per mole or grams per mole. It doesn't really matter because at the end it's all going to be um it's all going to be divided by one another. So actually given that it's all going to be divided, we really don't even need to substitute and for our so we can just keep this as our and this would be giving us then point 22 26 Radical three R. T. We really just want this coefficient here and then for root mean squared of neon, I'm sorry, I mean squared of krypton rather this would be equal to then again square root of three R. T. But this would be divided by here 83 .8 g per mole. So this is giving us then point 1092 radical three Rt. And then for right on we have Radical three RT. And this will be divided by here 222 g per mole. Giving us then .067 one radical three R. T. And at this point we can simply divide so root mean squared for neon root mean squared for krypton root mean square speed for raid on this would be equal to then .2226 .1092 .0671. And in order to get the whole number, we can simply divide all of these by .061. So divided by the smallest, essentially the smallest coefficient. And we find that this is going to be equal to then 3.32 To 1.63 21 So we can see that the rate root mean square root mean square speed of raden is the least And then root mean square of Krypton will be 1.63 times that of raden root. Mean squared of Neon will be 3.32 times that of raden. That is the end of the solution. Thank you for watching.
