What is k equal to in the equation r=k/(k-5)

i dont know if my answer is correct but this is probably your answer

Step-by-step explanation:

The equilibrium expression is the reciprocal of that given. If the coefficients in a balanced equation are multiplied by a factor, n, the equilibrium expression is raised to the nth power. K' is the constant for the reaction multiplied by n and K is the constant of the original reaction.

ratio is 2 : 9

the answer is three

13.5 : 3
