A chemical reaction is said to be in equilibrium when -
of the conversion has taken place
only conversion of X to Y has taken place
the rate of transformation of X to Y is equal to the rate of transformation of Y to X in the system
there is change in the concentration of either x or y
At equilibrium state, rate of forward reaction becomes equals to rate of reverse reaction
A chemical reaction X⇌Y is said to be in equilibrium when -
Which of the following observations helps to determine whether a chemical reaction has taken place or not?
(i) Change in state.
(ii) Change in colour.
(iii) Change in shape
(iv) Evolution of gas.
(v) Change in temperature.
