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

Answer:

$k_c_3$=1.21*$10^{24}$

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*$10^{24}$
