Monitoring of [h2(g)] during the course of the reaction • using the axes below, sketch a graph to show the results the initial rate of this reaction is 36 × 10–2 mol dm –3 s –1 calculate the rate constant, k, for this reaction state the units, if any. - rates of reaction the rate of reaction may be measured by following the loss of a reactant, or the formation of a product the rate of reaction is just how fast it goes we measure the rate of reaction by measuring the time taken for the reactants to be used up or products to be formed. Coursework rates of reaction research the rate of reaction tells us how quickly a chemical reaction takes place it is important for people in industry to know how fast a reaction goes they have to know exactly how much of their product they can make each hour, day or week.

Ocr a chemistry f325: rates, equilibrium and ph study play the rate of reaction at a certain point in the reaction can be deduced by drawing a tangent to the curve at the point in the reaction, and working out the gradient of that tangent by continuous measurements taken during the course of a reaction eg if a gas is given off.

Download from wwwocrorguk and included in the guide for controlled assessment for gcse twenty first century science) candidates’ reports should be annotated to show how marks have factors that affect the rate of reaction of calcium carbonate with acid controlled assessment information for candidates (1. Chemical equilibrium is a state in the course of a chemical reaction where the concentrations of both products and reactants reach the limit which prevents further deviation.

Rates of reaction energy - exothermic and endothermic what do exothermic and endothermic mean a chemical reaction always has a change in energy in a reaction going from reactants to products, either 1) heat is given out - called exothermic or 2) heat is taken in - called endothermic the large majority of chemical reactions are exothermic exothermic reactions give out heat to their.
