Answer to Question #274527 in Inorganic Chemistry for Gayathri

Question

The concentration of S2O3^2- used in the practical work 0.004M . If you were to triple this concentration, explain

if delta t would change

if reaction orders would change

Answer 1

The rate of a chemical reaction is defined as the rate of change in concentration of a reactant or product divided by its coefficient from the balanced equation. A negative sign is used with rates of change of reactants and a positive sign with those of products, ensuring that the reaction rate is always a positive quantity. In most cases, concentration is measured in moles per liter and time in seconds, resulting in units of M/s for the reaction rate. Created by Jay.
