Express the equilibrium constant for the combustion of ethanol in the balanced chemical equation.
C2H5OH(g)+3O2(g)⇌2CO2(g)+3H2O(g)
Express the equilibrium constant for the combustion of ethanol in the balanced chemical equation.
K=[CO2]2[C2H5OH][O2]3 |
K=[C2H5OH][O2][CO2][H2O] |
K=[CO2][H2O][C2H5OH][O2] |
K=[CO2]2[H2O]3[C2H5OH][O2]3 |
C2H5OH(g)+3O2(g)⇌2CO2(g)+3H2O(g)
Rate of forward reaction = Kf[C2H5OH][O2]^3
Rate of back ward reaction = Kb[CO2]^2[H2O]^3
At equilibrium rate of forward reaction = rate of back ward reaction
Kf[C2H5OH][O2]^3 = Kb[CO2]^2[H2O]^3
Kf/Kb = [CO2]^2[H2O]^3/[C2H5OH][O2]^3
Kc = [CO2]^2[H2O]^3/[C2H5OH][O2]^3 [ Kc = Kf/Kb]
K=[CO2]2[H2O]3/[C2H5OH][O2]3 >>>>>>answer
