Question
me: 17. An effective collision is one that results in the formation of products. Maxwell Boltzmann diagrams give relationship between fraction of molecules and energy. The fraction of molecules capable of effective colision, is given by the shaded position. Which of the following graphs correctly represents an effecetive collision? Fraction of molecules Fraction of molecules Fracton of molecules Fraction of molecules d. 18. Which of the following reactions is exothermic? d. ½ H2(g) + ½ 12(g) HI(g) AH . +26 kJ/mol 19. Consider the following activation energy diagram. From the above activation energy diagram it is seen that the reaction rate will temperature. The statement above is completed by information in row i at Row lower A. decrease decrease lower increase any E. stay the same d. D b. BExplanation / Answer
I hope option d is the correct answer.
Explanation: The activation energy is to give the reactants to get the activated complex, followed by products. More the fraction of reactant molecules capable of effective collision, then the corresponding graph represents an effective collision. In option a, few reactant molecules including products are capable of effective collision, hence the corresponding graph doen't represent effective collision. In option b, none of the reactant molecules but the products are capable of effective collision, hence the corresponding graph does also not represent an effective collision. In option c, all of the reactant molecules including product molecules are capable of effective collision, hence the corresponding graph involves the products to undergo certain other processes, which doen't represent an effective collision. Now, in the case of option d, only all the reactant molecules (no products) undergo effective collision, hence the corresponding graph correctly represents an effective collision.
