(a)
Interpretation:
On increasing the concentration of the reactant, the average energy of collision increases or not is to be identified.
(b)
Interpretation:
On increasing the concentration of reactant, the collision frequency increases or not is to be identified.
(c)
Interpretation:
On increasing the concentration of reactant, the fraction of collisions with proper molecular orientation increases or not is to be identified.
Explanation:
With an increase in the concentration of reactant, the number of molecules colliding increases and the space between these molecules decreases. Hence, the possibility of molecules colliding increases, which leads to an increase in the collision frequency. However, there is no increase in the fraction of molecules with proper orientation because there is no increase in the kinetic energy or temperature.
(d)
Interpretation:
On increasing the concentration of reactant, the fraction of collision with sufficient energy increases or not is to be identified.
Explanation:
With an increase in the concentration of reactant, the number of molecules colliding increases and the space between these molecules decreases. Hence, the possibility of molecules colliding increases. As the collision increases, the energy of molecules increases and molecules start colliding with sufficient energy to overcome the activation energy.
(e)
Interpretation:
On increasing the concentration of reactant, the reaction rate increases or not is to be identified.
Explanation:
With an increase in the concentration of reactant, the number of molecules colliding increases and the space between these molecules decreases. Hence, the possibility of molecules colliding increases. As the collision increases, the energy of molecules increases and molecules start colliding with sufficient energy to overcome the activation energy and more reactants get converted into products. This leads to an increase in the
(d)
Interpretation:
On increasing the concentration of reactant, the fraction of collision with sufficient energy increases or not is to be identified.
(e)
Interpretation:
On increasing the concentration of reactant, the reaction rate increases or not is to be identified.

EBK INTRODUCTION TO CHEMISTRY
- A mixture of C7H12O2, C9H9OCl, biphenyl and acetone was put together in a gas chromatography tube. Please decide from the GC resutls which correspond to the peak for C7,C9 and biphenyl and explain the reasoning based on GC results. Eliminate unnecessary peaks from Gas Chromatography results.arrow_forwardIs the molecule chiral, meso, or achiral? CI .CH3 H₂C CIarrow_forwardPLEASE HELP ! URGENT!arrow_forward
