The 'Dynamic balance rate' of forward process equals the rate of the backward (reversed) reaction
and
then
equilibrium
A reversible process is one which can be reversed and causes no changes in the system or surroundings. For a process in equilibrium, the rate of the forward process equals the rate of the reverse process (which can be, but is not necessarily equal to zero).
The balance is 2N2 +2O2= 4NO
(Explanation): Remember, changes are still occurring, but they occur at the same rate so that they effectively cancel each other out and there is no visible difference. The total number of reactants and products aren't fluctuating because they stay the same, that's what equilibrium means.

In any process, the material balance follows a universal equation: Accumulation = Input - Output + Generation The Generation term is omitted if we are talking about the overall mass (mass is nether created nor destroyed [unless it's a nuclear plant]), and the accumulation term can be omitted if we are at steady-state. Draw a box around the process that you want to consider and look at the inputs and outputs of each stream. The material balance can be solved if the number of equations equals the number of unknowns.
