Question

For the decomposition of nitrosyl bromide at 10 °C
2 NOBr(g) 2 NO(g) + Br2(g)
the average rate of disappearance of NOBr over the time period from t = 0 s to t = 14.1 s is found to be 3.51×10-3 M/s.

What is the average rate of appearance of Br2 over the same time period?

Answer 1

It is 2 times less, 1.755×10^-3 M/s.
