1. Learning Outcomes (Specific to the lesson mapped with NCERT learning outcomes):

After studying this Unit, you will be able to

1.Understand the concept of reaction rates and be able to (a)use the coefficients of a balanced chemical equation to express the rate of reaction in    terms of the change in concentration of a reactant or product over time. (b) distinguish between instantaneous rates and average rates from a graph.

2. Determine the rate law from initial rate data and be able to determine (a) the order of reaction with respect to each reactant.(b) the overall order of reaction. (c) the rate constant with units.

3. Recognize the integrated rate laws and be able to (a) use integrated first-order and second-order rate laws to find the value of one variable, given values of the other variables. (b)  explain the concept of reaction half-life and describe the relationship between half-life and rate constant for first-order and second-order reactions. (c) determine the order of the reaction from plots of concentration versus time, ln (concentration) versus time, and 1/(concentration) versus time.

4.Use Collision Theory to explain how reactions occur at the molecular level and (a) explain the concept of activation energy and how it relates to the variation of reaction rate with temperature.  (b) be able to interpret potential energy profiles and use them to determine the activation energy and potential energy changes for a reaction. (c) be able to use the Arrhenius equation to calculate a rate constant, activation energy, and frequency factor.

5.Define a catalyst and given a reaction mechanism, identify the reaction intermediate(s) and catalyst(s), write the overall reaction, and determine the molecularity of each step. describe the effect of a catalyst on the energy requirements for a reaction. sketch a potential energy profile showing the activation energies for the forward and reverse reactions and show how they are affected by the addition of a catalyst.

6. Explain how enzymes act as biological catalysts and how they interact with specific substrate molecules.

7. Explain why enzymatic reactions respond differently to temperature changes compared to non enzymatic processes.

B. Details of Pedagogical Strategies/Process (Art integrated /Sports integrated/ Story

          telling based/Toy based /Any other pedagogy):

1. Art integrated activity: Photography of different objects , rusted objects , trains ,busses different fast and slow moving vehicles etc the different materials /object  found  in daily life
2. Toy based process: electronic cars  comparison of their speeds
3. Sports integrated activities; 1.calculation  of speeds of different splinters. 2.bowling   speed comparision  in the cricket matches

• Topic of the lesson for presentation by the students (once in a week by  

Rearranging classroom setting suitable for group work):- Carrying out the activities in laboratory  different chemicals:-
