A graph given below deals with the revers-ible reaction. In which minute does the system attain equilibrium?

A graph given below deals with the revers-ible reaction. What happened to the forward and back-ward reactions as time passes?

A graph given below deals with the reversible reaction. : What inference can be drawn about the concentration of the reactants and products at the point D and E?

Select the correct statements which are re-latedto the influenceof catalystin a revers- ible reaction: Forward reaction takesplace when a catalyst is used in a reversible reaction.

Pick the correct statement from the following: the addition of a catalyst changes equilibrium constant., a catalyst speeds up the forward reaction but slows down the reverse reaction., the composition of equilibriụm is changed by catalyst., addition of catalyst does not change the equilibtium concentrations
