A 226.4-l cylinder contains 65.5% he(g) and 34.5% kr(g) by mass at 27.0°c and 1.40 atm total pressure. what is the mass of he in
Tems11 [2777]
Initially, we calculate the moles of gas using the ideal gas law:

PV = nRT
n = PV / RT
n = (1.4 * 226.4) / (0.082 *(27 + 273.15))
n = 12.88

Next, we apply the given percentages to estimate the moles of helium:
Moles of helium = 0.655 * 12.88
Moles of helium = 8.44

We then use the formula:
Mass = moles * molar mass

Mass of helium = 8.44 * 4

Mass of helium = 33.76 grams.

t-Butyl alcohol (TBA) is an important octane enhancer that is used to replace lead additives in gasoline [Ind. Eng. Chem. Res.,
alisha [2963]

The production mechanism for t-butyl alcohol proceeds as follows:

The reaction and corresponding rate law for isobutene adsorption on the Amberlyst-15 catalyst can be described by:

I + S ⇄ I * S -r_{ADI} = k_I(C_1C_v-\frac{C_{I.S}}{K_I} )

where C_V represents the concentration of unoccupied sites

K_I denotes the adsorption equilibrium constant

k_I indicates the forward rate constant

C_I,C_{I.S} are the concentrations of isobutene and the site occupied by isobutene

The equation for the adsorption of water (W) onto the Amberlyst-15 catalyst is outlined as:

W + S ⇄ W.S -r_{ADW} = k_W(C_WC_V-\frac{C_{W.S}}{K_W} )

The surface reaction's rate law can be described as:

W.S + I.S ⇄ TBA. S + Sn -r_s = k_s(C_{W.S}C_{I.S}-\frac{C_{TBA.S}C_V}{K_s} )

The desorption rate law for TBA from the catalyst is as follows:

TBA. S ⇄ TBA + S -r_{D TBA} = k_{DTBA}(C_{TBA.S}-\frac{C_{TBA}C_V}{K_{DTBA}} )

The image included below illustrates the rest of the steps.
