Answer:

3.3 x 10⁷.

Explanation:

  • For the reaction: <em>2CH₄(g) ⇄ C₂H₂(g) + 3H₂(g)</em>,

<em>Kc = 0.135 at 1608 °C.</em>

  • To get Kp, we can use the relation:

<em>Kp =Kc(RT)∧Δn.</em>

R is the general gas constant = 8.314 J/mol.K.

T is the temperature of the vessel = 1608 °C + 273 = 1881.0 K.

Δn =  no. of moles of gases in products - no. of moles of gases in the reactants = 4 - 2 = 2.

<em>∴ Kp =Kc(RT)∧Δn</em> = (0.135)[(8.314)(1881.0 K)]² = <em>3.3 x 10⁷.</em>

Which of the following statements about natural resources is correct
trasher [3.6K]

Answer:

The right choice is "wind power requires a lot of space and depends on local weather patterns "

Explanation:

  1. solar power produces harmful chemicals
  • it is incorrect because solar power doesn't produce any chemicals

    2. geothermal power requires more land than other power plants  

  •   it is incorrect because geothermal power requires digging a stable 5 km-deep shaft not a land

    3. nuclear power produces small amounts of energy from large masses

  • it is incorrect because nuclear power produces large amounts of energy from small masses.

So the right choice is "wind power requires a lot of space and depends on local weather patterns "

At what temperature a gas with volume 175 L at 15 oC and 760mmHg will occupy a volume of 198 L at a pressure 640mmHg?
MrRissso [65]

Answer:

To calculate the pressure when temperature and volume has changed, we use the equation given by combined gas law. The equation follows:

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

T

1

P

1

V

1

=

T

2

P

2

V

2

where,

P_1,V_1\text{ and }T_1P

1

,V

1

and T

1

are the initial pressure, volume and temperature of the gas

P_2,V_2\text{ and }T_2P

2

,V

2

and T

2

are the final pressure, volume and temperature of the gas

We are given:

\begin{gathered}P_1=760mmHg\\V_1=175L\\T_1=15^oC=[15+273]K=288K\\P_2=640mmHg\\V_2=198L\\T_2=?K\end{gathered}

P

1

=760mmHg

V

1

=175L

T

1

=15

o

C=[15+273]K=288K

P

2

=640mmHg

V

2

=198L

T

2

=?K

Putting values in above equation, we get:

\begin{gathered}\frac{760mmHg\times 175L}{288K}=\frac{640mmHg\times 198L}{T_2}\\\\T_2=274K\end{gathered}

288K

760mmHg×175L

=

T

2

640mmHg×198L

T

2

=274K

Hence, the temperature when the volume and pressure has changed is 274 K

The most probable mechanism of reactivity for the solvolysis of 2-chloro-norbornane is
velikii [3]

The rate determining step for the reactivity for the solvolysis of 2-chloro-norbornane depends only on the decomposition of a single molecular species which is the 2-chloro-norbornane itself. For unimolecular reactions, the mechanism pathway being followed is that of an SN1 mechanism.

 

Answer:

<span>SN1 mechanism</span>
