91166 Chemical Reactivity
What you'll learn
This course covers the things you'll need to know and be able to do for achievement standard 91166.
In it you'll find answers to questions like:
- What are the factors that affect rates of chemical reactions?
- What is meant by changes in reaction rate?
- How do you describe the dynamic nature of equilibrium?
- How do you predict the effect of changes to an equilibrium system?
- How do you interpret and explain the nature of acid-base solutions?
- How do you write equations for proton transfer reactions between acids and bases?
- How do you explain the behaviour of strong and weak acids and bases in terms of the concentration of ions?
- How are conjugate acid/base pairs identified?
- How do you account for the acidic or basic properties of some salts?
- How do you calculate pH for aqueous solutions?
- How to compare the properties of solutions of strong and weak acids and bases?
How you'll learn
There are a variety of ways you can learn and interact with the materials in this course.
Self-paced learning – the material is set up so you can learn at your own pace. Although there are 'suggested' times for each page, they're just a guideline - plan your learning to suit you.
Practice activities – throughout this course there are short activities. These activities are for you, not for someone to mark them. These activities give you a great chance to practise what you've learned and compare your answer to the model feedback. Look at the feedback carefully to see if you have missed out any aspects from your answer.
Submitting photos – sometimes people find it easier to scribble down a diagram or show their working with pen and paper. No problem! You can still store all your working and diagrams with the activity. That way you'll be able to refer back to your answers when you're revising. Simply take a photo of your work and upload it with the relevant activity.
