Kp for the reaction CO2(g) + C(s) --- 2CO(g) is 1.47 at 727°C. Calculate Kc at this temperature.

The correct answer is "0.0179".

Explanation:

The given reaction is:

⇒

The given value is:

At 727°C temperature,

Kp = 1.47

As we know,

Gas constant,

R = 0.0821 L atm/mol.K

Temperature,

=

=

Now,

The change in moles will be:

⇒

⇒      

⇒      

As we know,

⇒  

On substituting the given values, we get

⇒  

⇒    

⇒          

⇒          

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
