The answer actually has nothing to do with 1/t being an estimate, it's worked out practically. I'm doing the iodine clock reaction for my A2 chemistry coursework, and I thought that in order to work out the rate I would need to draw a concentration-time graph, draw a tangent to work out the rate and then from there draw a rate-concentration graph to check the order of the reaction...The temperature - When you raise the temperature of a system, the molecules bounce around a lot more (because they have more energy). There are quite a lot of students who get shivers down the spine at the very thought of chemistry.Students are taught in the same groups of 27 in which they were placed in at the start of Year 8. At the end of each year there will be an end of year examination.This will include testing work done in previous years, i.e.But if you are planning to work out the rate constant ,k, or other reaction kinematics it can lead to problems, if I remember correctly.This is because the reaction is rapid and the substrate concentration quickly declines. Comparison can only be made at the start of the reaction where controlled variables such as substrate concentration are the same for all levels of the independent variable. Those obtaining grade 8 or higher, will be eligible to continue studying Chemistry at A level.There is no longer a coursework element to GCSE Chemistry.The successful collisions have sufficient energy (activation energy - Ea) at the moment of impact to break the existing bonds and form new bonds, resulting in the products of the reaction.The variable heat for instance causes the particles to gain energy this causes higher chance for the particles to collide into each other.
