Answer: The mole ratio of \(Cl_2\) to \(Br_2\) in the given reaction is 1:1 .
Explanation: For a reaction the mole ratio is the ratio of their coefficients. Coefficients are the numbers used to balance the equations.
The given reaction is:
\(Cl2+2NaBr\rightarrow 2NaCl+Br_2\)
In this equation, the coefficient for each of \(Cl_2\) and \(Br_2\) is 1. So, the mole ratio of \(Cl_2\) to \(Br_2\) in the given reaction is 1:1 .
