Question

Enter your answer in the provided box.The following reactions have the indicated equilibrium constants at a particular temperature:N2(g)+ O2(g)⇌ 2NO(g)Kc = 8.3 ×10−252NO(g)+ O2(g)⇌ 2NO2(g)Kc = 6.4 ×109Determine the value of the equilibrium constant for the following equation at the same temperature:2NO(g)⇌ N2(g)+ O2(g)

Answer 1

`k_c_3`=1.21*
`10^(24)`

Step-by-step explanation:

`N_2+O_2 = 2NO K_c_1=8.3*10^-25`...................1

`2NO+O_2 = 2NO_2 K_c2 =6.4*10^9`………..2

`2NO=N_2+O_2 K_c_3`=? ………………………3

From the given reaction

Equation third is reverse reaction of first reaction

Hence
`K_c_3=1/K_c_1`

`K_c_3=1/(8.3*10^-25)`

`k_c_3`=1.21*
`10^(24)`
