I don’t really know this but I think
Answer : The concentration of NO is,
Solution : Given,
Concentration of and = 152 M
Equilibrium constant, =
The given equilibrium reaction is,
The expression of will be,
Now put all the given values in this expression, we get:
Therefore, the concentration of NO is,
(I think) you would have to divided the number i dont know the exact answer but ya hope this help
