Answer:

minimum number of trays:

N = 7 trays

Explanation:

minimum number (N):

  • N = ( Log ( (Xd / ( 1 - Xd ))  * (( 1 - Xb ) / Xb )) ) / Log α....Fenske's Eq. binary mixture

∴ α = 2.5

∴ Xd = 0.96.......molar fraction the distillate

∴ Xb = 0.04 .........molar fraction in the bottoms

⇒ N = ( Log  ( ( 0.96 / ( 1 - 0.96 ) ) * ( ( 1 - 0.04 ) / 0.04 )) ) / Log ( 2.5 )

⇒ N = 6.94 ≅ 7 trays

*Asap*
ira [324]

Answer:

(a).

order \: of \: A = 2 \\ order \: of \:B  = 0 \\ rate = k[A] {}^{2} [B]

(b)

0.32 \times  {10}^{ - 3}  = k {(0.12)}^{2} (0.15) \\ k = 0.148 \:  {mol}^{ - 2}  {dm}^{6}  {s}^{ - 1}

(c). The rate increases because kinetic energy of reactant molecules increases.

In the reaction, A → Products, the rate constant is 3.6 × 10−4 s−1. If the initial concentration of A is 0.548 M, what will be t
Arada [10]

Answer:

        \large\boxed{\large\boxed{0.529M}}

Explanation:

Since the <em>rate constant</em> has units of <em>s⁻¹</em>, you can tell that the order of the reaction is 1.

Hence, the rate law is:

       r=d[A]/dt=-k[A]

Solving that differential equation yields to the well known equation for the rates of a first order chemical reaction:

      [A]=[A]_0e^{-kt}

You know [A]₀, k, and t, thus you can calculate [A].

       [A]=0.548M\times e^{-3.6\cdot 10^{-4}/s\times99.2s}

       [A]=0.529M
