Definition: This is the amount of product we get at a given instant of time during or after the reaction.
Purpose: It helps chemists and chemical engineers determine the product yield at any point during a chemical reaction.
The calculator uses the formula:
Where:
Explanation: The moles of reactant consumed is multiplied by the instantaneous fractional yield to determine the moles of product formed.
Details: Calculating product moles helps in reaction monitoring, process optimization, and determining reaction efficiency at any point during the reaction.
Tips: Enter the moles of reactant consumed and the instantaneous fractional yield (between 0 and 1). The fractional yield represents the efficiency of conversion at that instant.
Q1: What is instantaneous fractional yield?
A: It's a measure of how selective a particular reactant is in forming a particular product at a certain instant during the reaction.
Q2: How is this different from overall yield?
A: Instantaneous yield measures efficiency at a specific moment, while overall yield measures the total efficiency over the entire reaction.
Q3: What does a fractional yield of 1 mean?
A: A yield of 1 (or 100%) means all the reacted reactant is being converted to the desired product at that instant.
Q4: Can the fractional yield change during a reaction?
A: Yes, the fractional yield often varies as the reaction progresses and conditions change.
Q5: How do I determine the instantaneous fractional yield experimentally?
A: It's typically determined by analyzing reaction samples at specific time points and measuring product/reactant ratios.
