For the reaction shown here, 5.7 molA is mixed with 3.2 molB and
2.5 molC. What is the limiting reactant?
3A+2B+C→2D
A
B
C
D
3A+2B+C→2D
A: B : C = 3 : 2: 1
C is exceses reactant
B is 3.2 moles = 3.2/2= 1.6 moles of B
5.7 moles of A = 5.7/3 = 1.9 moles of A
According to problem
A : B : C = 1.9 : 1.6: 2.5
Here limiting reagent is B
