Part A For the reaction 2CH4(g)⇌C2H2(g)+3H2(g) K = 0.140 at 1595 ∘C . What is Kp for the reaction at this temperature? Part B For the reaction N2(g)+3H2(g)⇌2NH3(g)

Homework Answers

Answer #1

2CH4(g)⇌C2H2(g)+3H2(g) K = 0.140

KP   = KC(RT)n

n = no of moles of products- no of moles of reactants in gases state

     = [1+3] -[2]

    = 2

R = 0.0821L-atm/mole_k

T = 1595C0 = 1595+273 = 1868K

KP = 0.14(0.0821*1868)2

    = 0.14*23520.14 = 3292.82 >>>> answer

Part- B

N2(g)+3H2(g)⇌2NH3(g)

KP   = KC(RT)n

n = no of moles of products- no of moles of reactants in gases state

     = 2-4 = -2

KP = 0.14(0.0821*1868)-2

    = 0.14/23520.14

    = 5.95*10-6

For chemical reactions involving ideal gases, the equilibrium constant K can be expressed either in terms of the concentrations of the gases (in M) or as a function of the partial pressures of the gases (in atmospheres). In the latter case, the equilibrium constant is denoted as Kp to distinguish it from the concentration-based equilibrium constant K.
