Question

Read the paragraph carefully and answer the questions given below it TO A catalyst increases the rate of chemical reaction by providing an alternative pathway which lower activation energy than the reaction pathway in its absen catalyst is not consumed and therefore does not appear in the chemical equation fo reaction A homogeneous catalyst is in the same phase as the reactants heterogeneous catalyst is in a different phase The complex Co NH3 sF 2 reacts with water according to the equation Co NH3 H O F and Rate K complex H Co NH3 F 2 H O The reaction is acid catalysed i e H does not change during the reaction Thus rate K Complex where K H Complex 0 1 0 2 H 0 01 0 02 From the above data value of a is A 1 C O 3 T172 hr 1 0 5 BA 2 D NI 2 T3 4 hr 2 1
