] , d H dt = k NH then the relation between k ,k and k is a) k = k = k b) k = k = k c) . k = k = k d) 2k = k = k . The decomposition of phosphine (PH ) on tungsten at low pressure is a first order reaction. It is because the (NEET) a) rate is proportional to the surface coverage b) rate is inversely proportional to the surface coverage c) rate is independent of the surface coverage d) rate of decomposition is slow .
For a reaction Rate = k acetone then unit of rate constant and rate of reaction respectively is a) mol L s mol L s
