Chemistry temperature changes practical
WebThere is some acceleration of the reaction rate due to the rise in temperature. Some students might notice the flask becoming slightly warm and they could be asked how this would affect the rate of reaction, and how they might adapt the experiment to make it a ‘fair test’. ... This is a resource from the Practical Chemistry project ... WebCalorimetry is a technique used to measure changes in enthalpy of chemical reactions A calorimeter can be made up of a polystyrene drinking cup, a vacuum flask or metal can A polystyrene cup can act as a calorimeter to find enthalpy changes in a chemical reaction
