From the rate expression for the following reaction, determine the order of reaction and the dimension of the rate constant.

\[\ce{H2O2_{( aq)} + 3I^-_{( aq)} + 2H^+ -> 2H2O_{(l)} + I^-_3}\] Rate = k[H2O2][I−]

उत्तर

Given rate = k[H2O2][I−]

∴ Order of the reaction = 2

Dimension of k = \[\ce{\frac{Rate}{[H2O2] [I-]}}\]

= \[\ce{\frac{(mol L^{-1} s^{-1})}{(mol L^{-1})(mol L^{-1})}}\]

= L mol−1 s−1
