Consider the following equilibrium: CO2(g) + C(graphite) 2CO(g); ΔH = 172.5 kJ The equilibrium constant for this reaction will
bezimeni [28]

Answer: Option (B) is the correct answer.

Explanation:

As the given reaction is as follows.

               CO_{2}(g) + C(graphite) \rightarrow 2CO(g)

Equilibrium constant for this reaction will be as follows.

             K_{c} = \frac{[CO_{2}]}{[CO]^{2}}

According to Le Chatelier's principle, when we increase the temperature then the equilibrium will shift towards the right hand side.

As a result, concentration of carbon dioxide will decrease whereas concentration of carbon monoxide will increase.

Thus, we can conclude that in the given reaction equilibrium constant for this reaction will decrease with increasing temperature.

How many moles of oxygen molecules are present in 112ml of co2 at NTP?​
dexar [7]

In each mole of carbon dioxide there will be one mole of O₂.

Let us calculate the moles of carbon dioxide gas present first

The conditions are NTP it means , Temperature = 293 K and P = 1 atm

We will use ideal gas equation

PV= nRT

Where

P = Pressure of gas = 1 atm

V= 112mL=0.112L

R= gas constant =0.0821 L atm /mol K

n = moles = ?

Putting values

moles=\frac{PV}{RT}=\frac{1X0.112}{0.0821X293}

moles = 0.00466

Thus moles of carbon dioxide will be 0.00466

The moles of O₂ = 0.00466

Which concept describes the formation of four equivalent, single, covalent bonds by carbon in its compounds that resembles metha
Montano1993 [528]
Carbon is special and unique because it is able to form different compounds with a lot of elements, including itself. When it bonds with itself, this is possible because of the concept of hybridization. It is the mixing of atomic orbitals into a new hybrid orbital. In this case, methane is formed through the sp³ hybridization.
