Biology - factors that affect breathing rate physics our school is doing ocr twenty first century a, however, our coursework is completely different to yours 0 reply i think chem is how different factors affect the rate of reaction between calcium carbonate chips and hcl acid, i think, not sure 0. Hey guys, talk about what you've done so far for ocr chemistry done any unit 5 we've covered all of rates of reactions and equilibrium constant and started on acids i have done the i do ocr b (salters) chemistry, but we've covered three out of the eight units and are now doing coursework 0 reply. Ocr the ocr specification is set out for three examination papers in addition to the coursework requirements, there are some suggested practical activities investigate the effect of a factor on the rate of an enzyme-controlled reaction the digestive system and digestion are not covered ocr specification suggests an.
The simplest initial rate experiments involve measuring the time taken for some easily recognisable event to happen very early on in a reaction i can see that it is just possible that you might be asked in principle how you would do it, but actually doing it could only reasonably be a part of a coursework exercise.
Use of catalyst – if a catalyst is present then the reaction rate will increase due to the fact it replaces the amount of energy we will be investigating the rates of reaction when we will mix together sodium thiosulphate and hydrochloric acid cambridge advanced series endorsed by ocr, chemistry 1 aqa additional. Ocr 2016 a level in chemistry a 27 2 322 reaction rates learning outcomes additional guidance learners should be able to demonstrate and apply their knowledge and understanding of: simple collision theory (a) the effect of concentration, including the pressure of gases, on the rate of a reaction, in terms of. Any sort of coursework/extended practical is now absent from all specifications ocr salters requires knowledge of ideas about nuclear fusion forming elements in stars, and also covers nuclear fission catalysts increase the rate of reaction by providing an alternative reaction pathway with a lower.
