Q. In the following reaction, which has maximum rate w.r.t. rate of disappearance of NH₃ ?
4NH₃ + 50₂   → 4NO + 6H₂ O

The rate of formation of NO(g) in the reaction, 2NOBr(g) →2NO(g) + Br₂ (g) was reported as 1.6 x 10^-4 Ms^-1 . Thus, rate of the reaction is  

Rate of formation of SO₃ in the  reaction below is 100 kg min^-1 .
2SO₂ + O₂  → 2SO₃
Hence, rate of disappearance of SO₂ will be:

The following reaction can take place in both directions:

For the forward reaction, the rate varies with the concentration of A as and for the backward reaction,

Hence, net reaction rate is:

For a reaction, xA →yB, rate of disappearance of ‘A ’is related to the rate of appearance of 'B 'by the equation  

Thus, x and y respectively are

For the reaction,

H₂ (g) + A₂ (g)   2H(g) + A₂ (g)

k_f = 2.2 x 10⁴ L mol^-1 s^-1  and K_c = 1.00 x 10^-4  at 3000 K. Thus, k_b is  

For a reaction,

hen x, y and z are  

For the reaction,

2N₂ O₅ (g) →4NO₂ (g) + O₂ (G)

Thus,

The decomposition of acetaldehyde is given by the following reaction:

CH₃ CHO(g) →CH₄ (g) + CO(g)

Rate of the reaction with respect to the pressure of the reactant is  

For the reaction, 

 then rate law is
