A reaction in which A,B ,C and react to form products is first order in A, second order in B, and zero order in C. What is the overall order of the reaction? By what factor does the reaction rate change if A is doubled (and the other reactant concentrations are held constant)? By what factor does the reaction rate change if C is doubled (and the other reactant concentrations are held constant)? By what factor does the reaction rate change if the concentrations of all three reactants are doubled?
