OCR 21C REVISION: C5 in under 15 minutes

# data[].attributes.attachment_link.description
THIS VIDEO IS FOR OCR 21st CENTURY SCIENCE (From 2012) NEW: Link to mind map (for video): http://dl.dropbox.com/u/34683196/C5%20mindmap.jpg This video aims to cover most (not all!) of C5 in under 15 minutes. It is in the form of a 'mind map', which you should be using as part of your revision 'repertoire', to help test what you know, highlight what you don't, and action plan your revision.

The final assessment opportunity for this qualification (J244) will be summer 2017.

This qualification provides the opportunity to further develop understanding of scientific explanations, how science works and aspects of chemistry relevant to careers in science. This qualification provides distinctive and relevant experience for learners who wish to progress to Level 3 qualifications.

064 - Equilibrium In this video Paul Andersen explains how equilibrium is achieved in a reversible reaction. When the rate of the forward reaction is equal to the rate of the reverse reaction the system is at equilibrium. Graphical analysis of equilibrium is included along with a walkthrough of several calculations.

Topics

Description

Watch a reaction proceed over time. How does total energy affect a reaction rate? Vary temperature, barrier height, and potential energies. Record concentrations and time in order to extract rate coefficients. Do temperature dependent studies to extract Arrhenius parameters. This simulation is best used with teacher guidance because it presents an analogy of chemical reactions.

Sample Learning Goals

Describe on a microscopic level, with illustrations, how reactions occur.

Describe how the motion of reactant molecules (speed and direction) contributes to a reaction happening.

Predict how changes in temperature, or use of a catalyst will affect the rate of a reaction.

On the potential energy curve, identify the activation energy for forward and reverse reactions and the energy change between reactants and products.

Sketch how the concentrations of reactants and products change as a reaction proceeds.

From a graph of concentration as a function of time, students should be able to identify when a system has reached equilibrium.

Calculate a rate coefficient from concentration and time data.

Determine how a rate coefficient changes with temperature.

Compare graphs of concentration versus time to determine which represents the fastest or slowest rate.
