What is the RMS velocity of hydrogen at NTP?

If R.M.S. velocity of hydrogen molecule at N.T.P. is 1840m/s, determine the R.M.S. velocity of oxygen molecule at N.T.P. (molecular weight of hydrogen and oxygen are 2 and 32, respectively).

What is the RMS velocity of hydrogen at 27 degree Celsius?

The r.m.s velocity of hydrogen at 27∘C, R = 8.314 J mol−1K−1 is. A. 1.934 ms−1. B.

What is the formula of RMS velocity?

It is represented by the equation: vrms=√3RTM v r m s = 3 R T M , where vrms is the root-mean-square of the velocity, Mm is the molar mass of the gas in kilograms per mole, R is the molar gas constant, and T is the temperature in Kelvin.

How do you calculate the rms speed of hydrogen?

RMS speed is inversely proportional to the square root of mass (molecular or molar). This means the rms speed of hydrogen should be √16 = 4 times faster….solution.

Why hydrogen has maximum RMS speed at NTP?

Answer: RMS speed is inversely proportional to the square root of molecular mass when temperature is constant. Since hydrogen has least molecular mass, it has highest RMS speed at NTP.

What is the density of hydrogen at NTP?

Basic Hydrogen Properties

What is the root mean square speed of oxygen molecules at 27?

760 cm s-
The root mean square speed of oxygen at 27°C is 760 cm s-

What is r in 3RT M?

urms = SQRT (3RT/M) In the 2nd expression, R is the universal gas constant. The universal gas constant = 8.31 J mol-1 K-1 (i.e., one of the values that you see on the data packet).

What is M in 3KT M?

Speed V of the molecules of an ideal gas is given by the expressions, v = sqrt (3RT/M) and v = sqrt (3KT/m) where R is universal gas constant, T is the absolute (Kelvin) temperature M is the molar mass, K is Boltzman’s constant and M is the molecular mass.

What is the velocity of a hydrogen molecule?

At standard temperature and pressure the mean speed of hydrogen molecules is 1.70 × 103 ms−1.
