Answer:  Convection is the process of warm fluids rising and cooler fluids sinking. Inside the Earth, convection is powered by heat mostly from the core. The slow circulation of rock in the mantle moves the tectonic plates at the surface.

Consider the reaction C2H4(g) + H2O(g) --> CH3CH2OH(g)
arsen [322]

Answer:

K = 361.369

Explanation:

C2H4(g) + H2O(g) → CH3CH2OH(g)

∴ ΔG°f(298.15K) CH3CH2OH(g) = - 174.8 KJ/mol

∴ ΔG°f(298.15) C2H4(g) =  68.4 KJ/mol

∴ ΔG°f(298.15) H2O(g) = - 228.6 KJ/mol

⇒ ΔG°f(298.15) = - 174.8 - ( - 228.6 + 68.4 ) = - 14.6 KJ/mol

  • K = e∧(-ΔG°f / RT)

∴ R = 8.314 E-3 KJ/mol.K

∴ T = 298.15 K

⇒ K = e∧(-(-14.6)/((8.314 E-3)(298.15)))

⇒ K = e∧(5.889)

⇒ K = 361.369

The Haber Process is the main industrial procedure to produce ammonia. The reaction combines nitrogen from air with hydrogen mai
Firdavs [7]

Answer:

A) N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g).

B) Kc=0.0933.

C) 0.9 mol.

D) Increasing both temperature and pressure.

Explanation:

Hello,

In this case, given the information, we proceed as follows:

A)

N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)

B) For the calculation of Kc, we rate the equilibrium expression:

Kc=\frac{[NH_3]^2}{[N_2][H_2]^3}

Next, since at equilibrium the concentration of ammonia is 0.6 M (0.9 mol in 1.5 dm³ or L), in terms of the reaction extent x, we have:

[NH_3]=0.6M=2*x

x=\frac{0.6M}{2}=0.3M

Next, the concentrations of nitrogen and hydrogen at equilibrium are:

[N_2]=\frac{1.5mol}{1.5L}-x=1M-0.3M=0.7M

[H_2]=\frac{4mol}{1.5L}-3*x=2.67M-0.9M=1.77M

Therefore, the equilibrium constant is:

Kc=\frac{(0.6M)^2}{(0.7M)*(1.77M)^3}\\ \\Kc=0.0933

C) In this case, the equilibrium yield of ammonia is clearly 0.9 mol since is the yielded amount once equilibrium is established.

D) Here, since the reaction is endothermic (positive enthalpy change), one way to increase the yield of ammonia is increasing the temperature since heat is reactant for endothermic reactions. Moreover, since this reaction has less moles at the products, another way to increase the yield is increasing the pressure since when pressure is increased the side with fewer moles is favored.

Best regards.

3. A 50.0 L sample of gas collected in the upper atmosphere at a pressure of 18.3 mmHg is compressed into a 150.0 mL container a
pochemuha

Answer:

a. P_2=8.03atm

b. V_2=0.024L=24mL

Explanation:

Hello,

a. In this case, we use the Boyle's law as en inversely proportional relationship between pressure and volume:

P_1V_1=P_2V_2

Thus, for the given conditions, one computes the new pressure as shown below:

P_2=\frac{P_1V_1}{V_2} =\frac{18.3mmHg*50.0L}{150.0mL*\frac{1L}{1000mL} }*\frac{1atm}{760mmHg} \\ \\P_2=8.03atm

b. Now, we should find the final volume for a new pressure of 10 atm:

V_2=\frac{P_1V_1}{P_2} =\frac{50.0L*18.3mmHg*\frac{1atm}{760mmHg} }{50atm}\\ \\V_2=0.024L=24mL

Best regards.

Which is given as an example for how the paleozic supercontinent ice cap melted?
serg [7]

 

An example for how the Paleozic supercontinent ice cap melted is through plants dying off, which in turn, increased the greenhouse effect.

 

To add, <span>the trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface is called the greenhouse effect.</span>
