Can anyone tell me the method to use to calculate the rate of reaction between potassium bromate and bromide ions (using sulphuric acid)? I will be varying the temperature and concentration.
Thankyou!

This is an ionic (electron transfer) reaction, so the reaction kinetics are extremely fast. The rate will be mass transfer limited. In other words, it depends on how fast the reactant molecules can come in contact each other. Temperature will be a factor in the speed with which the KBrO3 dissolves.

Good luck

it rather is a question related to Le Chatelier's thought which states that as quickly as a tension is utilized to a reaction at equilibrium, equilibrium will shift to alleviate the stress. earlier answering this question, you will desire to undergo in recommendations the thank you to write down the Keq expression. undergo in recommendations that it rather is comparable to the products divided by potential of reactants, each and every raised to the capacity equivalent to the coefficient interior the balanced equation. additionally undergo in recommendations that solids are actually not risk-free in Keq!! A. because of the fact NaHCO3 is a stable, it is not risk-free interior the Keq expression and consequently would not impact equilibrium. consequently, it won't shrink the water vapor. B. whilst CO2 is extra, the equilibrium is disturbed, and the reaction will shift in the direction of the left as a fashion to apply up this extra CO2. nicely, whilst the CO2 is used, it additionally makes use of H2O and Na2CO3, so this might shrink the water vapor. C. shrink the quantity of the container fairly will advance the stress that it rather is decrease than. Le Chatelier's says that as a fashion to alleviate this bigger tension the reaction will proceed in the direction of the ingredient with the LEAST style of gas molecules. this means that the reaction will back shift to the left, making use of up the water vapor (reducing the concentration). D. because of the fact the enthalpy for this reaction is +136kJ all of us realize it rather is an endothermic reaction. It potential that warmth is fairly a reactant. So if the container is cooled, Le Chatelier's says that the reaction will shift to make extra warmth (to change the warmth that became into lost) and the thank you to do it is to shift in the direction of the left (considering the fact that we wrote warmth as a reactant and we would desire to make extra of it). moving this way will dissipate the water vapor and shrink its concentration.
