Answer:
Value of is 0.090.
Explanation:
Initial molarity of =
= 0.0700 M
Construct an ICE table corresponding to the combustion reaction of carbon to determine
I (M): - 0.0700 0
C (M): - -x +2x
E (M): - 0.0700-x 2x
So, , where [CO] and
represents equilibrium concentration of CO and
respectively.
Here,
⇒x = 0.030
So, = 0.0700-x = (0.0700-0.030) = 0.040
Hence,
