A sample of nitrosyl bromide (nobr) decomposes according to the equation 2nobr(g)⇌2no(g)+br2(g) an equilibrium mixture in a 5.00

Alex73 [517]

Answer:

Kc = 0.122.

Explanation:

We can calculate Kc from the relation: Kc = [NO]².[Br₂] / [NOBr]².

Firstly, we convert the number of grams of each component to moles using <em>(n = mass / molar mass)</em>.

n of NOBr = (3.26 g / 109.8 g/mole) = 0.03 moles.

n of NO = (3.06 g / 29.9 g/mole) = 0.102 moles.

n of Br₂ = (8.15 g / 159.9 g/mole) = 0.051 moles.

Then we can get the concentration of each component by dividing its no. of moles by the volume of the vessel <em>(concentration = n / V)</em>.

The concentration of NOBr = (0.03 mole / 5.00 L) = 6x10⁻³ mol/L.

The concentration of NO = (0.102 mole / 5.00 L) = 2x10⁻² mol/L.

The concentration of Br₂ = (0.051 mole / 5.00 L) = 1x10⁻² mol/L.

Now, we can get Kc:

Kc = [NO]².[Br₂] / [NOBr]² = (2x10⁻² mol/L)².(1x10⁻² mol/L) / (6x10⁻³ mol/L)² = 0.122.

Consider the equation for the formation of water. 2h2 o2 right arrow. 2h2o what is the theoretical yield of h2o if 130 g of h2o

Montano1993 [528]

The theoretical yield is the reaction yield that measures the product of the reaction from the conversion of the limiting reagent. The theoretical yield is 160 gm.

Mass or the theoretical yield is the result of the multiplication of mole and the molar mass of the compound.

The reaction between hydrogen and oxygen is shown as,

$\rm 2H_{2} + O_{2} \rightarrow 2H_{2}O$

Moles of water is calculated as:

$\begin{aligned}\rm moles &= \rm \dfrac{mass}{molar\; mass}\\\\&= \dfrac{18}{2}\\\\&= 9\;\rm moles\end{aligned}$

The theoretical yield of water is calculated as:

$\begin{aligned}\rm \text{weight of water} &= \rm moles \times molar \; mass\\\\&= 9 \times 18\\\\&= 162 \;\rm gm\end{aligned}$

Therefore, option D. 160 gm is the theoretical yield of water.
