Reason for why gaseous Bromine is reddish brown and transparent whereas liquid Bromine is dark brown and passing of light is little has to be explained using postulates of Kinetic-molecular theory.

(b)

Interpretation Introduction

Interpretation:

Reason for why when equal volumes of gaseous $B{r}_2$ and $N_2$ at the same temperature and pressure are brought into contact, they mix rapidly and the color is only half as dark as the initial $B{r}_2$ colour has to be explained using postulates of Kinetic-molecular theory.
