Monochromatic light literally means Light of one color.
The Answer you're looking for here is Star A mainly because it's the star with the highest Surface Temperature on the Graph.
The reaction equation is already balanced. So the mole ration of reactants and production is the ratio of the coefficients. So the mole ratio of N2 to NO2 is 1:2.
The balanced equation
for the reaction is
CO(g) + 2H₂(g) ⇄ CH₃OH(g)
The given
concentrations are at equilibrium state. Hence we can use them directly in
calculation with the expression for the equilibrium constant, k.
expression for k can be written as
k = [CH₃OH(g)] / [CO(g)] [H₂<span>(g) ]²
</span>[H₂<span>]=0.072 M
[CO]= 0.020M
[CH</span>₃OH]= 0.030 M
From substitution,
k = 0.030
M / 0.020 M x (0.072 M)²
k =
289.35 M⁻²
<span>
Hence, equilibrium constant for the given reaction at 700 K is 289.35 M</span>⁻².
