The slope of the tangent at a point on the curve of concentration of a reactant as a function of time gives the instantaneous rate of reaction.

For a reaction, the instantaneous rate of reaction with respect to x, y and z is expressed as r=-(1)/(2)(Delta[x])/(Delta t)=-(1)/(3)(Delta[y])/(Delta t)=(1)/(2)(Delta [z])/(Delta t) . What would be the stoichiometric equation for the reaction ?
