Answer:
B.) ![K_{eq} = \frac{[SO_3][NO]}{[SO_2][NO_2]}](https://tex.z-dn.net/?f=K_%7Beq%7D%20%3D%20%5Cfrac%7B%5BSO_3%5D%5BNO%5D%7D%7B%5BSO_2%5D%5BNO_2%5D%7D)
Explanation:
The general equilibrium expression looks like this:
![K_{eq} = \frac{[C]^c[D]^d}{[A]^a[B]^b}](https://tex.z-dn.net/?f=K_%7Beq%7D%20%3D%20%5Cfrac%7B%5BC%5D%5Ec%5BD%5D%5Ed%7D%7B%5BA%5D%5Ea%5BB%5D%5Eb%7D)
In this expression,
-----> K = equilibrium constant
-----> uppercase letters = formulas
-----> lowercase letters = balanced equation coefficients
The products are in the numerator and the reactants are in the denominator. Since all of the molecules are gases, they should all be included in the expression. Since the coefficients in the balanced equation are all 1, they do not need to be represented in the expression.
The equilibrium constant expression is:
![K_{eq} = \frac{[SO_3][NO]}{[SO_2][NO_2]}](https://tex.z-dn.net/?f=K_%7Beq%7D%20%3D%20%5Cfrac%7B%5BSO_3%5D%5BNO%5D%7D%7B%5BSO_2%5D%5BNO_2%5D%7D)

Answer:
C = 0.5621J/g°C
Explanation:
Heat lost by metal = Heat gained by water
Heat gained by water;
H = MC ΔT
ΔT = 28 -25 = 3.0°C
M = 130.0g
C = 4.18 J/g°C
H = 130 * 4.18 * 3 = 1639J
Heat lost my metal;
H = MCΔT
ΔT = 100 - 28 = 72°C
M = 40.5g
C = ?
C = H / MΔT
C = 1639 / (40.5 * 72)
C = 0.5621J/g°C
