. Write the rate equation for the reaction 2A + B C, if the order of the reaction is zero.

According to the law of mass action, the rate of a chemical reaction at a constant temperature depends only on the concentrations of the substances that influence the rate
The rate of the reaction is the sum of the power of the exponent in the rate law expression
for the reaction
2A+B ------->C
rate is given by = k[A]^x[B]^y
here the order of the reaction is 0,therefore rate of the reaction is 0.In other words it is a zero order reaction.
oredr=0
x+y=0
x=-y
rate=k(A/B)^x
