The formula for most probable velocity is. Vrms vav and vmp are root mean square average and most probable speeds of molecules of a gas obeying Maxwellian velocity distribution. As stated above C mp is the most probable speed thus it will be at the top of the distribution curve.

At what temperature will most probable speed of the molecules of the second member of homologous series C n H 2n2 be the same as that. Most probable speed since the largest fraction of molecules move at this speed hence it is the most probable speed. Most probable speed is the speed at the top of Maxwell-Boltzmann Distribution curve because the largest number of molecules have that speed is calculated using Most probable speedsqrt2RTemperature of GasMolar MassTo calculate Most probable speed you need Temperature of Gas T and Molar Mass MWith our tool you need to enter the respective value for Temperature of Gas and. If is defined as the most probable speed then v th 2 k B T m.
