Which of the following expressions is correct for the rate of reaction given below?
5Br- (aq) + BrO3– (aq) + 6H+ (aq) → 3Br2 (aq) + 3H2O(l)
1
\(\rm \frac{\Delta[Br^-]}{\Delta t}=5\frac{\Delta[H^+]}{\Delta t}\)
2
\(\rm \frac{\Delta[Br^-]}{\Delta t}=\frac{6}{5}\frac{\Delta[H^+]}{\Delta t}\)
3
\(\rm \frac{\Delta[Br^-]}{\Delta t}=\frac{5}{6}\frac{\Delta[H^+]}{\Delta t}\)
4
\(\rm \frac{\Delta[Br^-]}{\Delta t}=6\frac{\Delta[H^+]}{\Delta t}\)
