Haemoglobin (Hb) react with carbon monoxide according to the following equation. Give its rate equation. 4Hb + 3CO → Hb4(CO)3

Can this be done without knowing the mechanism?

This is how the question was

rate = 0.25*change in concn Hb/change in time or

rate = d(Hb)/4*dT

To determine the rate equation for the reaction between haemoglobin (Hb) and carbon monoxide (CO), we need to examine the reaction rate and how it is affected by the concentrations of the reactants.

The rate equation expresses the relationship between the rate of a reaction and the concentrations of the reactants. In this case, the rate equation will include the concentrations of haemoglobin and carbon monoxide.

To determine the rate equation, we need experimental data where the initial concentrations of the reactants are varied, and the corresponding reaction rates are measured. By comparing the reaction rates at different concentrations, we can determine the effect of the concentrations on the rate of the reaction.

Once we have the experimental data, we can use the method of initial rates or the method of continuous variation to determine the rate equation. These methods involve comparing the initial rates of the reaction at different concentrations or varying the concentrations of the reactants while keeping their ratio constant, respectively.

By analyzing the data, if we find that the reaction rate is directly proportional to the concentration of haemoglobin raised to the power of 1 (Hb^1) and the concentration of carbon monoxide raised to the power of 1 (CO^1), then the rate equation for the reaction would be:

Rate = k[Hb]^1[CO]^1

Note that the powers to which the concentrations are raised in the rate equation correspond to the stoichiometric coefficients in the balanced equation (4Hb + 3CO → Hb4(CO)3). However, without experimental data, we cannot determine the exact rate equation for this particular reaction.

Therefore, to determine the rate equation for the reaction between haemoglobin and carbon monoxide (4Hb + 3CO → Hb4(CO)3), experimental data and analysis are required.
