Number Objective Rates of Reaction Define the term rate of reaction. Describe suitable experimental procedures for measuring rates of reactions. Analyze data from rate experiments. Students should be familiar with graphs of changes in concentration, volume and mass against time. Collision Theory Describe the kinetic theory in terms of the movement of particles whose average energy Is proportional to the temperature In Kelvin's.

Define the term activation energy (EAI).

Describe the collision theory. Students should know that reaction rate upends on: 0 Collision frequency 0 Number of particles with E > EAI 0 Appropriate collision geometry or orientation Predict and explain, using collision theory, the qualitative effect of particle size, temperature, concentration, and catalysts on the rate of a reaction. State and explain qualitatively the Maxwell-Balletomane energy distribution curve for a fixed amount of gas at different temperatur


es and Its consequence for changes in the reaction rate.

Deduce the rate expression for a reaction from experimental data. Solve problems Involving the rate expression.

Sketch, Identify, and analyze graphical representations for zero, first, and second-order reactions. Students should be familiar with both concentration-time and rate-concentration graphs.

2. 2 Reaction Mechanism

Explain that reactions can occur in more than one step and that the slowest step determines the rate of the reactions (rate-determining step).

Describe the relationship between reaction mechanism, order of reaction, and the mechanism is given will be assessed. Activation Energy Describe qualitatively the relationship between the rate constant  and temperature (T). Determine activation energy values from the Awareness equation by a graphical method. The Awareness equation: data booklet.

And its logarithmic form are provided in the chemistry
