The rate equation for the reaction  2A+B→C  is found to be : rate = K[A][B]. The correct statement in relation to this reaction is

(1) Rate = K[A][B]     (2) Rate constant (k) depends only on temperature and catalyst.(3)  2A + B → C   Rate formation of 'C' is half the rate of disappearance of 'A'(4)  for 2nd order             only option (2) is correct.
