Question

mathematical expression of rate of chemical reaction

Answer 1

Answer:

mathematical expression

Reaction rate thus defined has the units of mol/L/s. The rate of a reaction is always positive. A negative sign is present to indicate that the reactant concentration is decreasing. ... For example, if a = 1 and b = 3 then B is consumed three times more rapidly than A, but v = -d[A]/dt = -(1/3)d[B]/dt is uniquely defined.
