Questions on Rate & Consumption

For the reaction 2A + B to C, rate of disappearance of A 0.076 mols^-1. What is the rate of consumption of B?

The gas - phase reaction between NO and Br_(2) is respresented by the equation 2NO_((g)) + Br_(2(g)) to 2NOBr_((g) (a ) Write the expressions for the rate of consumption of reactants and formation of products. ( b) Write the expression for the rate of overall reaction in terms of rates of consumption of reactions and formation of products.

The rate of formation of NO(g) in the reaction NOBr(g) rarr NO(g) + Br_(2)(g) is found to be 1.6 xx 10^(–4) M//s . Find the rate of overall reaction rate and rate of consumption of NOBr.
