1.72 moles of NOCI were placed in a 2.50 L reaction chamber
elena-14-01-66 [18.8K]

The equilibrium constant, Kc=0.026

<h3>Further explanation</h3>

Given

1.72 moles of NOCI

1.16 moles of NOCI  remained

2.50 L reaction chamber

Reaction

2NOCI(g) = 2NO(g) + Cl2(g).

Required

the equilibrium constant, Kc

Solution

ICE method

   2NOCI(g) = 2NO(g) + Cl2(g).

I    1.72

C   0.56           0.56         0.28

E   1.16              0.56         0.28

Molarity at equilibrium :

NOCl :

\tt \dfrac{1.16}{2.5}=0.464

NO :

\tt \dfrac{0.56}{2.5}=0.224

Cl2 :

\tt \dfrac{0.28}{2.5}=0.112

\tt Kc=\dfrac{[NO]^2[Cl_2]}{[NOCl]^2}\\\\Kc=\dfrac{0.224^2\times 0.112}{0.464^2}=0.026

What is the percent composition of carbon in heptane c7h16
Gnom [1K]

Answer: the percent composition of carbon in heptane is 83.9%

Explanation:

<u>1) Atomic masses of the atoms:</u>

  • C: 12.01 g/mol
  • H: 1.008 g/mol

<u>2) Molar mass of heptane:</u>

  • C₇H₁₆: 7 × 12.01 g/mol + 16×1.008 g/mol = 100.2 g/mol

<u>3) Mass of carbon in one mole of heptane:</u>

  • C₇: 7 × 12.01 g/mol = 84.07 g/mol

<u>3) Percent composition of carbon:</u>

  • % = (mass in grams of C) / (mass in grams of C₇H₁₆) × 100 =

           = (84.07 g/ 100.2 g) × 100 = 83.9% ← answer
