Consider the following statements : (i)increase in concentration of t

1.	Consider the following statements : (i)increase in concentration of the reactant increases the rate of a zero order reaction. (ii) rate constant k is equal to collision frequency A if E_a= 0 (iii) rate constant k is equal to collision frequency A if E_a= @ (iv) a plot of ln (k) vs (1/T) is a straight line with a positive slope. Correct statements are ............
Answer» (ii) only (ii) and (IV) (ii) and (v) (i) , (ii) and (v) Solution :In zero order reactions, increase in the concentration of REACTANT does not alter the rate . So STATEMENT (ii) is correct, and statement (iii) is wrong `k=Ae^0` if `E_a=0` (so, statement (ii) is correct , and statement (iii) is wrong `k=Ae^0` k = A LN `k=A-((E_a)/(R))(1/T)` this equation is in the form of a straight line equation y = c + mx a plot of LNK vs `(1/T)` is a straight line with negative slope so statements (iv) and (v) are wrong .
