For a reversible reaction `H_2(g) + I_2(g) overset(k_1) underset (k_2) harr 2HI` derive an expression for the formation of HI.

For the reaction , 2HI hArr H_(2) + I_(2)

For a reaction N_(2(g)) + 3H_(2(g)) hArr 2NH_(3(g))

Reaction beween NO _(2) and F _(2) to give NO _(2) F takes place by the following machanism: NO _(2) (g) + F _(2) (g) overset( "slow") to NO _(2) F (g) + F (g) , NO _(2) (g) + F _(2) (g) overset("Fast") to NO _(2) F (g) Wiite the rate expression and order of the rection.

For a reaction : 2NH_3(g) overset (Pt) rarr N_2(g)+3H_2(g) Rate =k . Write the order and molecularity of this reaction.

Consider the chemical reaction, N _(2) (g) + 3 H _(2)(g) to 2 NH _(3) (g). The rate of this reaction can be expressed in terms of time derivative of concentration of N _(2) (g), H _(2) (g) or NH _(3) (g). Identify the correct relationship amongest the rate expression.

For the reaction O_(3(g)) + O_((g)) rarr 2O_(2(g)) , if the rate law expression is, rate = K[O_3] [O] , the molecularity and order of the reaction are respectively

For a reaction A overset (k) rarr product, the reaction occurs as : A overset (k_1) rarr A^(**) overset (k_2) rarr B^(**) overset (k_3) rarr product The overall rate constant k is given as: k= 2k_1 (k_2/k_3)^(2//3) If E_(a1) , E_(a2) and E_(a3) are the activation energies of these steps, then what is the relation between overall activation energy E_(a) and the activation energies of these steps.

For the reaction H_(2)(g)+I_(2)(g)hArr2HI(g) the equilibrium constant K_(p) changes with
