Question

For the reaction, 2X+3Y=
4Z   , the rate of reaction may be represented as​

Answer 1

Answer:

As per the stoichiometry, 2 moles of X should react with 3 moles of Y and 4 moles of Z.

However, only 1 mole of X is present for 3 moles of Y and 4 moles of Z.

Hence, X is the limiting reagent.

1 mole of X will react with 1.5 moles of Y and 2 moles of Z to produce 2.5 moles of W.

However, only 1.25 moles of W are obtained.

Hence, the percentage yield is

2.5

1.25

×100=50 %.
