The aqueous-phase decarboxylation of CH2NO2CO2H, CH2NO2CO2H CH3NO2(aq) + CO2(g), is studied at a certain temperature, giving the following data: Time (s) [CH2NO2CO2H] (M) 0.0e+00 0.100 1.0e-01 0.0466 2.0e-01 0.0217 3.0e-01 0.0101 4.0e-01 0.00473 Figure out whether this reaction is first-order or second-order with respect to the concentration of CH2NO2CO2H. Calculate the value of the rate constant. Pick the choice from below which gives the correct reaction order and value of the rate constant for this reaction.
Below is a proposed mechanism for ClO–(aq) reacting with I–(aq) in the presence of OH–(aq). ClO- +H2O --> HOCl +OH- (fast, reversible)I- +HOCl --> HOI +Cl- (slow)HOI + HO- --> IO- +H2O You are trying to show that the rate law for this proposed mechanism matches an experimentallydetermined one. What is the expression for koverall or k’ for the proposed mechanism?Note: When writing an expression, H2O is not involved (just don’t include it).
