law of mass action

Which of the following statements are correct: (i) law of mass action and rate law expressions - are same for single step reaction (ii) the slowest step of a complex reaction gives the order of the complex reaction (iii) both order and molecularity have normally a maximum value of 3 (iv) m olecularity of a com plex reaction A + 2B to C is 3

The low of mass action applicable to heterogenous equilibria.

In which of the following reaction, law of mass conservation is not valid

According to the third law of motion , action and reaction

A : According to Newton's third law of motion for every action, there is an equal and opposite reaction. R : There is no time lag between action and reaction.

The action and reaction forces referred to Newton's third law of motion
