Rate law or rate equation defined as the product of rate constant (K) and the concentration of its reactants. For example A → product Rate law =k [A] For example A+B → product Rate law =k [A][B] For example A +A→ product Rate law =k [A] [A] Rate law =k [A]^2 Similarly For example nA → product Rate law =k [A][A] [A][A] ....... n times of[A] Rate law =k [A]^n

The Steady-State Approximation. ... The steady-state approximation is a method used to derive a rate law. The method is based on the assumption that one intermediate in the reaction mechanism is consumed as quickly as it is generated. Its concentration remains the same in a duration of the reaction.

2nd rxn ke Expression me check karo stoichiometry is in power though it is rate law equation

reshav we have to check here the production rate of intermediate and consumption rate of intermediates and make them equal
- Like(0)
so in 3rd expression you take production rate

isme check karo sir rate law equation me B ki jo stoichiometry hai bo power me likhi hai

yes reshav it is comsumption rate of B...so as you find rate eqn...similarly you do here
- Like(0)
but you must multiply the moles of B i.e is 2 here in right side

You have also done right reshav... It is similar like case which you do in chemical kinetics in writing rate law equation
