7.2.1

I can deduce the equilibrium constant K_c for homogenous reactions:

3.       Answer the following questions:

a.      What can change the value of K_c

b.     The reaction must be at ____________ for the value of K_c to be calculated

c.      Define the term homogeneous

d.    Rule for unit of Kc

a)The value of Kc can only be changed by changing the temperature.
b)The reaction must be at equilibrium for the value of Kc to be calculated.
c)The term homogeneous means when the products and the reactants are all in the same state.
d)(c+d)-(a+b)=0, then no units
    (c+d)-(a+b)=1, then unit of moldm-3
    (c+d)-(a+b)=-1, then unit of mol-1dm3
