IB Chemistry IA (1).pdf - Title: The Effect of Changing As temperature increases, the rate of reaction increases as the particles have more kinetic energy so collide more often, and these collisions are more likely to result in a successful reaction. Now many students are having to cope with an investigation based on secondary data. It should be clear from these guidelines that you need to choose your own project and completely own it. Does the titration temperature affect how accurately the Mr of a hydrated salt can be determined using redox titration? Does thermal decomposition allow unknown salts to be identified? For example, does increasing size of an alkyl group attached to the central atom have an effect? Does the lattice enthalpy of different salts affect how effectively they melt ice?
