When I invert the concentration of say this equation:
2HCr4- + 3HS03- + 5H+ -> 2Cr3+ + 3SO4^2- + 5H20.
and get RSRRE wrt HS03-, the rates of reactants is positive and the rates of products is negative.
If say it is wrt HS03- which gives it a coefficient of 1 and you are trying to get the ratee of say Cr3+, would the rate be changed back to a positive number? Or will it stay negative?
RSRRE = Relative stoichiometric rxn rate expression.
