reactions
In an instance where mg is reacting with HCl and citric acid is reaction with NaHCO3. how to decide which is faster is the temperature difference of the or the ΔH used
Well it depends on the conditions (temperature, concentration, etc) but assuming it does not (same conditions) then I reckon the more exothermic the more faster the rate is.
But it also depends on the activation energy and the total entropy change and whether it's a reversible reaction where laws of mass action applies.
So it's best to go with experience. Generally it is observed that organic reactions are slower than inorganic ones. You could also base your answer on the reactivity or strength of the substances.
In this case the former is faster than the latter.
1. The former is an inorganic reaction while the latter is organic
2. Mg is a metal and fairly reactive one
3. HCl is a stronger acid than citric acid.
