1.	Which of the following correctly depicts the fact that identical chemical equilibrium can be attained through reversible reaction H_2+I_2=2HI from either direction?
Answer» Solution :If `1 mol` of `H_2` and `1 mol` of `I_2` are taken in bulb `I` at `500^@C` and `2 mol` of `HI` are taken in an identical bulb `II` at `500^@C`, the intensity of COLOUR in I decreases due to the consumption of `I_2` while the intensity of colour in II INCREASES due to the formation of `I_2`. Ultimately, both have the same intensity of COLOR. In all these graphs, `t_c` is the time at which equilibrium is attained.
