Asked by Danielle

Two colourless solutions are mixed in a stoppered flask. as the reaction proceeds, the resulting solution turns red, and a colourless gas is formed. after a few minutes, no more gas is evolved but the red colour remains. what evidence is there that equilibrium has been established?
Answered by DrBob222
No more gas is evolved. Intensity of the red color does not change.
