Provide the expressions for the equilibrium constant Keq: CH4(g) + 2H2SE(g) ⇄ 4H2(g) +CSe2(g)

Chemistry
1 answer:
Sloan [31]4 years ago
3 0

Answer:

Keq = [H₂]⁴[CSe₂]/[CH₄][H₂Se]².

Explanation:

  • The equilibrium constant expression is the ratio of the concentrations of the products over the reactants.

  • For the reaction:

<em>CH₄(g) + 2H₂Se(g) ⇄ 4H₂(g) + CSe₂(g).</em>

<em></em>

<em>∴ Keq = [products]/[reactants] = [H₂]⁴[CSe₂]/[CH₄][H₂Se]².</em>

PLEASE HELP

The right answer is high number of offspring produced. asexual reproduction only requires on orgainism and creates an identical copy leaving no room for an increase of intelligence. plus it creates much more offspring and more often than sexual reproduction.

How many molecules are there in 45.0 grams of CH ?
Sonbull [250]

Answer:

There are 1.8021 ⋅ 1024 molecules of CH4 in 48 grams of CH4. To answer this question, you must understand how to convert grams of a molecule into the number of molecules. To do this, you have to utilize the concepts of moles and molar mass. A mole is just a unit of measurement. Avogadro's number is equal to 6.022 ⋅1023 molecules/mole. i think please dont complain to me if its wrong im sorry

In an electrochemical cell, which direction to the electrons flow?
Jet001 [13]

Answer:

Electrons flow from anode to cathode (this is always the case). For an electrolytic cell however, this flow is not spontaneous but must be driven by an external power source. In an electrolytic cell, the anode has the "+" sign.

Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pr
Nesterboy [21]

<em> Charles's Law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pressure conditions</em>

<h3><em>Further explanation</em></h3>

There are several gas equations in various processes:

  • 1. The general ideal gas equation

PV = nRT

PV = NkT

N = number of gas particles

n = number of moles

R = gas constant (8,31.10 ^ 3 J / kmole K

k = Boltzmann constant (1,38.10 ^ -23)

n = = N / No

n = m / M

n = mole

No = Avogadro number (6.02.10 ^ 23)

m = mass

M = relative molecular mass

  • 2. Avogadro's hypothesis

In the same temperature and pressure, in the same volume conditions, the gas contains the same number of molecules

So it applies: the ratio of gas volume will be equal to the ratio of gas moles

V1: V2 = n1: n2

2. Boyle's Law

At a fixed temperature, the gas volume is inversely proportional to the pressure applied

p1.V1 = p2.V2

  • 3. Charles's Law

When the gas pressure is kept constant, the gas volume is proportional to the temperature

V1 / T1 = V2 / T2

  • 4. Gay Lussac's Law

When the gas is heated in a tube whose volume does not change, the gas pressure in the tube is proportional to its absolute temperature

P1 / T1 = P2 / T2

  • 5. Law of Boyle-Gay-Lussac

Combined with Boyle's law and Gay Lussac's law

P1.V1 / T1 = P2.V2 / T2

P1 = initial gas pressure (N / m2 or Pa)

V1 = initial gas volume (m3)

P2 = gas end pressure

V2 = the final volume of gas

T1 = initial gas temperature (K)

T2 = gas end temperature

So the correct answer is Charles' Law, where at constant pressure, the volume of gas will be inversely proportional to its temperature
