Question

Which of the following are correct? 1. The fraction of collisions with energy greater than or equal to the activation energy always doubles as the temperature, on the Kelvin scale, is doubled. 2. The probability of correct relative orientation in collisions is smaller for reactants with complicated shape than for reactants with simple shape. 3. The rate determining step in a reaction mechanism must be an elementary process. 4. The rate determining step in a reaction mechanism cannot be the first step. O A. 1 and 3 only O B.2 and 4 only O C. 1,3 and 4 only O D. 1 and 2 only O E. 2 and 3 only

Answer 1

10 which are correct & The fraction of collisions with energy greater than or equal to the activation energy always doubles as the temperature on the Kelvin scale is double This is true, for reactants with complicated - As big Collision ve probability of correct relative Orientation. - in collisions is Smaller for reactants with shape than reactants with simple shape o This is true or compux struture molentes. number of effective collisions is dow - small molentes righer effeipti ③ The Rate determining step in a - mechanism most be elementony procesa 7 This is false false » Because Because RDS Ros postep may be C Ast-order, and order even in Zero order, 6 The Rate determining step in a reaction cannot be step in a reaction determining false - at may ast step, middle step, first steps I This is false - at may ast step, 1 cs Sash step, So correct statement- are and Answers 0 1 and 2 only,
