Answer #1

A)

T= 41.0 oC

= (41.0+273) K

= 314 K

delta n = number of gaseous molecule in product - number of gaseous molecule in reactant

delta n = -5

Kp= Kc (RT)^delta n

Kp = 85.2*(0.0821*314.0)^(-5)

Kp = 7.48*10^-6

Answer: 7.48*10^-6

B)

T= 179.0 oC

= (179.0+273) K

= 452 K

delta n = number of gaseous molecule in product - number of gaseous molecule in reactant

delta n = -1

Kp= Kc (RT)^deltan

0.0139 = Kc *(0.0821*452.0)^(-1)

Kc = 0.516

Answer: 0.516

The equilibrium constant, Kc, is calculated using molar concentrations. For gaseous reactions another form of the equilibrium constant, Kp, is calculated from partial pressures instead of concentrations. These two equilibrium constants are related by the equation Kp=Kc(RT)Δn where R=0.08206 L⋅atm/(K⋅mol), T is the absolute temperature, and Δn is the change in the number of moles of gas (sum moles products - sum moles reactants).
