Question

At 

−9.01°C

 the concentration equilibrium constant 

Kc

 

=9.5

 for a certain reaction.

Here are some facts about the reaction:

  • Some of the reactants are liquids and solids.
    • The net change in moles of gases is 
      −2
      .

  • If the reaction is run at constant pressure, 
    118./kJmol
     of heat are absorbed.

 

Using these facts, can you calculate 
Kc
 at 
15.°C
?
 
Yes.
 
 
No.
 
If you said yes, then enter your answer at right. Round it to 2 significant digits.
 
If you said no, can you at least decide whether 
Kc
 at 
15.°C
 will be bigger or smaller than 
Kc
 at 
−9.01°C
?
 
Yes, and 
Kc
 will be bigger.
 
 
Yes, and 
Kc
 will be smaller.
 
 
No.
