Which statement correctly describes the actual yield and the theoretical yield of a reaction?

a.) the actual yield is calculated from the reactant amounts, but the theoretical yield must be measured for each instance of a reaction.

b.)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.

c.)the actual yield depends on the reaction conditions, but the theoretical yield varies only with reactant amounts.

d.)the actual yield represents the maximum yield possible, and the theoretical yield assumes perfect reaction conditions.

Answer : Option C) The actual yield depends on the reaction conditions, but the theoretical yield varies only with reactant amounts.

Explanation : The theoretical yield of any reaction depends upon the stoichiometric calculation based on the number of moles of all reactants participating in reaction.

The actual yield is the yield which is obtained after the reaction, in which the amount actually produced of a product is the actual yield of the reaction. When a ratio of actual yield to theoretical yield is taken and is expressed in percent it is called percent yield.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
