Given the equation representing a system at equilibrium N2(g)
RoseWind [281]

Answer:

  • <u>Decreasing the temperature of the system will shift the reaction rightward.</u>

Explanation:

The complete question is:

Given the equation representing a system at equilibrium:

  • N₂(g) + 3H₂(g) ⇌ 2NH₃(g) + energy

what changes occur when the temperature of this system is decreased?

<h2>Solution</h2>

Modifying the temperature of a system in equilibrium changes the equilibrium constant and the equilibrium position (concentrations) of the system.

When the temperature is decreased, following LeChatelier's principle that the system will react in a way that seeks to counteract the disturbance, the reaction will shift toward the reaction that produces more heat energy to compensate the temperature decrease.

Thus, decreasing the temperature of the system will favor the forward reaction, more N₂(g)  and H₂(g) will be consumed and more NH₃(g) and energy will be produced. Hence, the equilibrium will shift rightward.

Which of the following can form an aqueous solution that conducts electricity?
julia-pushkina [17]

Answer:

Pb(NO3)2

Explanation:

  • Compounds that conduct electricity either in the aqueous or molten form are known as electrolytes.
  • Electrolytes conduct electricity due to the presence of mobile ions.
  • Electrolytes are, therefore, decomposed by passing an electric current through them, a process known as electrolysis.
  • Lead(ii) nitrate can form an aqueous solution that conducts electricity also known as an electrolyte.
  • It ionizes in water to generate lead ions and nitrate ions which are responsible for the conducting of electricity.

Add a temperature of -33.0 Celsius a sample of a confirmed gas eggs or to pressure of 0.5 to 6 ATM if it's volume remains consta
Levart [38]

<u>Answer:</u> The final temperature of the gas is -220.6°C

<u>Explanation:</u>

To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1\text{ and }T_1 are the initial pressure and temperature of the gas.

P_2\text{ and }T_2 are the final pressure and temperature of the gas.

We are given:

P_1=6atm\\T_1=-33^oC=[273-33]K=240K\\P_2=1.31atm\\T_2=?

Putting values in above equation, we get:

\frac{6atm}{240K}=\frac{1.31atm}{T_2}\\\\T_2=\frac{1.31\times 240}{6}=52.4K

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

T(K)=T(^oC)+273

52.4=T(^oC)+273\\\\T(^oC)=-220.6^oC

Hence, the final temperature of the gas is -220.6°C
