For the reaction, 2H_2 (g )+2 NO (g ) N_2 (g )+2H_2O (g ) the observed rate expression is, rate =k_f [ NO ]^2 [H_2 ]. The rate expression for the reverse reaction is:

Question

Accepted Answer

Correct answer: C. (c) 2H_2 (g )+2 NO (g ) ⇔N_2 (g )+2H_2O (g ) K_c= k_fk_b= [N_2 ] [H_2O ]^2 [H_2 ]^2 [ NO ]^2 Given for forward reaction, rate =k_f [ NO ]^2 [H_2 ] For reverse reaction rate =k_b [N_2 ] [H_2O ]^2/ [H_2 ]

$For the reaction, 2 H_{2} (g) + 2 NO (g) \to N_{2} (g) + 2 H_{2} O (g) the observed rate expression is, rate = k_{f} [NO]^{2} [H_{2}] . The rate expression for the reverse reaction is:$
