Solution-Factors that influence the rate of reaction

Factors that influence the rate of reaction

Reference no: EM132403775

What are the independent and controlled variables in these factors that influence the rate of reaction

a. Reactant concentration

Mg strips placed in 4 different concentrations of HCl

b. Surface are

The reaction between sodium bicarbonate and citric acid (the ingredients in alka-seltzer tablets) when dissolved in water will be used to determine the impact of surface area on the rate of the reaction. You will measure the time it takes for the cap on a canister to pop. The formula for citric acid is H3C6H5O7. You can treat this reaction like a double displacement reaction initially. Citric acid is a triprotic acid with the citrate ion as the polyatomic ion in the acid.

c. Catalyst

The reaction uncatalyzed and catalyzed reaction between solutions of KI, Na2S2O3 and KBrO3 will be used to demonstrate the impact of a catalyst on the rate of a reaction. Ammonium molybdate, (NH4)2MoO4, is the catalyst used in this reaction.

d. Nature of reactants

The reaction between different metals (Zn, Cu, and Mg) and 6 M hydrochloric acid will be used to determine the impact of the nature of the reactant on reaction rate. Use about 10 mL of the acid for each trial.
