(a)
Interpretation:
The activation energy value of the given reaction has to be calculated.
Concept Introduction:
Activation energy:
The minimum amount of energy required to start a given
(b)
Interpretation:
Whether the given reaction is exothermic or endothermic has to be identified.
Concept Introduction:
Exothermic reaction:
If heat is released during a chemical or physical change those reactions are called as exothermic reactions.
Endothermic reaction:
If heat is absorbed during a chemical or physical change those reactions are called as endothermic reactions.
(c)
Interpretation:
For the given reaction the plausible structure of transition state has to be given.
(d)
Interpretation:
The effect of temperature on the given reaction rate has to be explained.
Concept Introduction:
Activation energy:
The minimum amount of energy required to start a given chemical reaction is known as activation energy.

- . Account for the increase in reaction rate brought about by a catalyst.arrow_forwardAccount for the relationship between the rate of a reaction and its activation energy.arrow_forwardThree first-order reactions have the following activation energies: (a) Which reaction is the fastest? (b) Which reaction has the largest half-life? (c) Which reaction has the largest rate?arrow_forward
- . What does the activation energy for a reaction represent? How is the activation energy related to whether a collision between molecules is successful?arrow_forwardHow do the rate of a reaction and its rate constant differ?arrow_forwardConsider a reaction in which E a=129 kJ and H=29 kJ. In the presence of a catalyst, the activation energy is 48% of the uncatalyzed reaction. Follow the directions in Question 71 in drawing an energy diagram.arrow_forward
