CHEMICAL KINETICS 1 MARKS QUESTIONS

Each question contains STATEMENT-1 (Assertion) and STATEMENT-2( Reason). Examine the statements carefully and mark the correct answer according to the instruction given below: STATEMENT-1:For a chemical reaction at initial stage rate of forward reaction ( r_(f) ) is greater than rate of reversed reaction( r_(b) ) STATEMENT-2: When r_(f)=r_(b) ,chemical reaction is at equilibrium.
