Two main aspects that determine if successful are:
1. Collisions must have sufficientenergy.
2. Collisions must occur in a correctorientation.
Increase temperature will increase the averagekinetic energy of particles, increase the frequency of collisions, increase proportion of particle with sufficient energy to react. Therefore, increase reaction rate
Higher surface area will more‘stuff’ to bump into, increase the frequency of collisions, thus higher reaction rate.
Increase catalyst will create alternativereactionpathway, low activation energy, and increase the proportion of successfulcollisions. Therefore, higher reaction rate.
Compare Extension Reaction and Rate of Reaction
Extension Reaction: Indicates the amount of productformed when the system reaches equilibrium.
Rate Reaction: Measure of [Reactants] and [Products] over a period of time.
Q > Kc, a net reverse reaction is occurring to regain/reachequilibrium.
Q < Kc, a net forward reaction is occurring to reachequilibrium.
Le Chatelier’s Principles :
‘If a change is applied to an equilibrium system, the equilibrium will shift to partiallyoppose the effects of that change.’
