(b) Nitrosyl bromide, NOBr, is formed from NO and Br2. Balance the equation for this reaction.NO + Br2 NOBrThe reaction is second order in NO and first order in Br2. Write down the rate law for the reaction What is the effect on the initial rate of changing the Br2 concentration from 0.0022 mol L-1 to 0.0011 mol L-1? The rate of the reaction is 1.5 mol L-1 s-1 when the concentration of NO and Brs are both 0.0022 mol L-1. Calculate the rate constant.
