SUMMARY

The discussion centers on identifying the limiting reagent in the chemical reaction A + B2 --> AB2, given 2 moles of A and 3 moles of B. The correct limiting reagent is B, as 3 moles of B correspond to 1.5 moles of B2, which reacts with only 1.5 moles of A, leaving 0.5 moles of A unreacted. The confusion arises from the book's assumption of 3 moles of B2 instead of the 3 moles of B provided in the problem statement.

PREREQUISITES
  • Understanding of stoichiometry in chemical reactions
  • Knowledge of limiting reagents in chemical equations
  • Familiarity with mole conversions in chemical reactions
  • Basic principles of chemical reaction balancing
NEXT STEPS

Homework Statement


IN A REACTION
A + B2 --> AB2

IF 2 mol A and 3 mol B is taken identify the limiting reagent.



Homework Equations


3 mol B means 1.5 mol of B2 which would react with 1.5 mol of A and 0.5 mol of A will be left
and hence l.r is B
the book says A.
help please





The Attempt at a Solution

 
Physics news on Phys.org
Could be the book assumes 3 moles of B2, but it is not what is stated in the question. 3 moles of B and 3 moles of B2 are different things and question should be clear on that. For me your answer is the right one.
 
hmmm...thankyou sir
