Which statement correctly describes the actual yield and the theoretical yield of a reaction?The actual yield is calculated from the reactant amounts, but the theoretical yield must be measu for each instance of a reaction.The actual yield is calculated from the amount of the limiting reactant, and the theoretical yield is calculated from the amount of the excess reactant.The actual yield depends on the reaction conditions, but the theoretical yield varies only with reactant amounts.The actual yield represents the maximum yield possible, and the theoretical yield assumes perfect reaction conditions.

Answer: The actual yield depends on the reaction conditions, but the theoretical yield varies only with reactant amounts.The actual yield has to be detemined from the real data.The theoretical yield is calculated with the reactants amoounts and the theroretical molar ratios indicated by the chemical equation. Thus, the theoretical yield is the maximum possible yield, from the total reaction of the limiting reactant. The actual yield must be detemined under the particular contitions on which the reaction is performed.
