Identify the correct labels of A , B and C in the following graph from the options given below: Root mean square speed V r m s ; most proable speed V m p ; Average speed V a v

A - V mp ; B - V av ; C - V rms

A - V mp ; B - V rms ; C - V av

A - V av ; B - V rms ; C - V mp

A - V rms ; B - V mp ; C - V av

For gaseous state, if most probable speed is denoted by C * , average speed by C ¯ and root mean square speed by C , then for many molecules, what is the ratios of these speeds?

C * : C - : C = 1 : 1 .128 : 1 .225

C * : C - : C = 1 : 1 .225 : 1 .128

C * : C - : C = 1 .225 : 1 .128 : 1

C * : C - : C = 1 .128 : 1 .225 : 1
