Benzene and toluene form ideal solutions. Consider a solution of benzene and toluene prepared at 25∘C. As suming that the mole f

ractions of benzene and toluene in the vapor phase are equal, calculate the composition of the solution. At 25∘C the vapor pressures of benzene and toluene are 95 and 28 torr, respectively.

Answer:

Xtoluene = 0.77

Xbenzene = 0.23

Explanation:

Step 1: Data given

Temperature = 25.0 °C

the mole fractions of benzene and toluene in the vapor phase are equal

At 25∘C the vapor pressures of benzene and toluene are 95 and 28 torr.

Step 2:

Xtoluene + Xbenzne = 1

Since the mol fractions are equal, the partial pressure also will be equal.

pToluene = pbenzene

Xtoluene *pToluene = Xbenzene *pBenzene = (1.00 - Xtoluene)*pBenzene

⇒with X toluene = mol fraction of toluene

⇒pbenzene = vapor pressure benzene = 95 torr

⇒Xbenzene = mol fraction benzene = 1.0 -0.5

⇒ptoluene = 28 torr

Xtoluene * 28 torr = (1.0 - Xtoluene)*95 torr

Xtoluene = 0.77

Xbenzene = 1.0 - 0.77 = 0.23

SO2Cl2 decomposes by first order kinetics and k=2,81x106-3 min-1 at a given temperature. The initial concentration of SO2Cl2=0.0
solmaris [256]

Answer:

246.67 min

Explanation:

Half life is the time at which the concentration of the reactant reduced to half.

Half life expression for first order kinetic is:

t_{1/2}=\frac {ln\ 2}{k}

Where, k is rate constant

So,  

Given that;- k = 2.81\times 10^{-3}\ min^{-1} (Values corrected from source)

Thus,

t_{1/2}=\frac{\ln2}{2.81\times 10^{-3}\ min^{-1}}=\frac{\ln2}{2.81\times 10^{-3}}\ min

t_{1/2}==355.87188\ln \left(2\right)\ min=246.67\ min

<u>246.67 min is the half-life of the reaction.</u>

What is the pH of a bleach solution that has a [OH−]=1.3×10−4 M?
Delvig [45]

Answer:

pH = 10.113

Explanation:

Here, we can find pOH first:

pOH = -log([OH^-]) = 3.886.

Then, we can find pH which is 14 - pOH. We then get the answer above.

Consider the following balanced equation:3Ca(NO3)2(aq) + 2Na3PO4(aq) → Ca3(PO4)2(s) + 6NaNO3(aq)If 24.2 moles of Na3PO4(aq) reac
Tomtit [17]

Answer:

69.7% is percent yield

Explanation:

Based on the reaction:

3Ca(NO3)2(aq) + 2Na3PO4(aq) → Ca3(PO4)2(s) + 6NaNO3(aq)

2 moles of Na3PO4 react producing 6 moles of NaNO3.

As 24.2 moles of Na3PO4 react, theoretical moles of NaNO3 produced are:

24.2 moles Na3PO4 * (6 moles NaNO3 / 2 moles Na3PO4) =

72.6 moles of NaNO3

As there are produced 50.6 moles of NaNO3, percent yield is:

50.6 moles NaNO3 / 72.6 moles NaNO3 =

<h3>69.7% is percent yield</h3>
