R According to stoichiometry, 2 moles of x yields 5 moles of w. 1 mole of x yield(5/2) =2.5 moles of w % yield=( textActual yield/ textyield obtained) × 100 =(1.25/2.5) ×100 =50 %

Q. For the reaction
$2 x + 3 y + 4 z \to 5 w$
Initially if $1$ mole of $x, 3$ moles of $y$ and $4$ moles of $z$ is taken. If $1.25$ moles of $w$ is obtained then $%$ yield of this reaction is

$50%$

$60%$

$70%$

$40%$

$∴ x$ is $L . R$
According to stoichiometry, $2$ moles of $x$ yields $5$ moles of $w$ .
$1$ mole of $x$ yield $\frac{5}{2} = 2.5$ moles of $w$
$%$ yield $= \frac{Actual yield}{yield obtained} \times 100$
$= \frac{1.25}{2.5} \times 100 = 50%$

Q. For the reaction 2x+3y+4z→5w Initially if 1 mole of x,3 moles of y and 4 moles of z is taken. If 1.25 moles of w is obtained then % yield of this reaction is

50%

60%

70%

40%
