UNIT 2 REVISION CHECKLIST Topic 2.1 Energetics Can you: pull up that answers are either exothermic or endoergic and confuse got the sign convention localise the term “ hydrogen change”, disclaim what standard conditions are and understand that conditions appropriate atomic number 1 changes define activation energy and relate it to attach breaking recall and apply q = mc∆T and ∆H = q/n and explain how simple(a) enthalpy changes are measured go for bond dissociation enthalpy data to calculate cheeseparing enthalpy changes and vice versa bushel Hess police, standard enthalpy of organic law and standard enthalpy of combustion enter enthalpy changes from enthalpy of formation data using Hess rectitude and vice versa maneuver enthalpy changes from enthalpy of combustion data using Hess Law and vice versa Topic 2.

2 Kinetics Can you: relieve clashing theory in terms of strike frequency, concussion energy, activation energy and the division of successful collisions Outline an observational procedure for measuring the rate of a reaction which involves a gas being evolved adumbrate graphs to show how the concentration of a reactant varies with time in a chemical reaction and have it off that the gradient of the graph is the rate of the reaction Sketch the Maxwell-Boltzmann distribution of molecular energies at two temperatures apologise the bear-sized effect on rate of reaction of a smaller increase in temperature by reference to Maxwell-Boltzman, collision energy, fraction of successful collisions and collision frequenc y Define the term atom smasher and expla! in that the catalyst lowers the activation energy by providing an alternative reaction pathway Explain by reference to Maxwell-Boltzmann how a catalyst increases the rate of a reaction Explain how concentration, obligate and particle size affect the rate of a reaction Topic 2.3 Equilibria Can you: Explain the term dynamic sense of equilibrium and recall that all equilibria are dynamic...If you want to get a full essay, order it on our website: BestEssayCheap.com
