I know from feedback that my gcse science summary revision pages have proved useful but they do not guarantee a high grade, that all depends on you and the factors mentioned in point 4. Please note that my GCSE science revision pages are designed to be used for online convenience, so, beware, printouts could be quite long!

Some quizzes, particularly the compilations, are quite large and take some time to download. Links to specific GCSE chemistry notes and quizzes about the topic in question have been added, and from these pages, you may find other links to more useful material linked to the topic.

In terms of old grades the following is an approximate comparison: Whilst the reactivity of chemicals is a significant factor in how fast chemical reactions proceed, there are many variables that can be manipulated in order to speed them up or slow them down.

Chemical reactions may also be reversible and therefore the effect of different variables needs to be established in order to identify how to maximise the yield of desired product. Understanding energy changes that accompany chemical reactions is important for this process.

In industry, chemists and chemical engineers determine the effect of different variables on reaction rate and yield of product.

Whilst there may be compromises to be made, they carry out optimisation processes to ensure that enough product is produced within a sufficient time, and in an energy efficient way.

Factors affecting the rate of a chemical reaction - temperature, concentration, particle size, catalysts etc. You should be able to: In the context of rates of reaction data, you must be able to Recognise and use expressions in decimal form. Use ratios, fractions and percentages. Make estimates of the results of simple calculations.

What is Science?

Translate information between graphical and numeric form. Plot two variables from experimental or other data. Determine the slope and intercept of a linear graph.

Draw and use the slope of a tangent to a curve as a measure of rate of change.By Elmer Beauregard.

Climate Change and Global Warming Introduction — Global Issues

Know the rate of a chemical reaction can be found by measuring the quantity of a reactant used or the quantity of product formed over time. What is science? Science is the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding is done through observation of natural phenomena, and/or through experimentation that tries to simulate natural processes under controlled conditions.

The International Geosphere-Biosphere Programme (IGBP) will come to a close at the end of this year after three decades of fostering international collaborative research and synthesis on global change. Here, Kahan et al. propose that the answer stems from the fact that climate-change isn't part of our jobs.

In fact, for billions of us non-specialists, our understanding of climate change has.
