Interpretation:
The fraction of the molecules in a gas at 300 K, which collide with energy equal to or greater than Ea. and the fraction of the molecules in the gas at the same temperatureif Ea is doubled should be identified.
Concept introduction:
Based on collision theory, a reaction takes place because the reactant molecules collide with each other. However, if the collision is not effective, it does not turn into products. Hence, in order to achieve a product, there must be effective collision taking place. If any molecule can perform effective collisions, there must be some energy. This energy is always greater than the minimum energy of a molecule possesses called Threshold Energy. Any energy which greater than this energy is called Activation Energy, which isa must to form a product from the reactants.
Therefore, Activation Energy = Threshold Energy − Average kinetic energy of reactants.
From the given Activation Energy, we can calculate the number of fraction of molecules in any of the gaseous reaction at a given temperature.
Given:
Temperature = 300K
Activation Energy = Ea = 50 kJ/mol.
Activation Energy = Ea = 100 kJ/mol.

- What would be the best choices for the missing reagents 1 and 3 in this synthesis? 1. PPh3 3 2. n-BuLi • Draw the missing reagents in the drawing area below. You can draw them in any arrangement you like. • Do not draw the missing reagent 2. If you draw 1 correctly, we'll know what it is. • Note: if one of your reagents needs to contain a halogen, use bromine.
