C5.1 Monitoring Chemical Reactions What is the yield of a reaction? What is meant by the theoretical yield? How would you calculate the theoretical yield if you knew the masses of the starting materials used? C5.1 Monitoring Chemical Reactions Links  C3.1 Introducing Chemical Reactions C3.3 Types of Chemical Reactions  C6.1 Improving processes and products What is meant when we say a reactant is in excess? What is a limiting reactant? What is the formula for calculating concentration of a solution: In mol/dm3? In g/dm3? Draw and label the equipment used in a titration State 5 factors that are important when deciding which reaction pathway to use? 1. 2. 3. 4. 5. Percentage yield Formula: Why is a high percentage yield desirable? Atom economy Formula: Why is a high atom economy desirable? Similarities What is the formula for converting volume of gas to number of moles? Write the method for carrying out a titration How do you convert: cm3 to dm3? dm3 to cm3? Differences How much volume does one mole of gas occupy at room temperature and pressure? Keywords
