HCl Solving for Concentration Reaction Mixture 1
HCl Solving for Concentration Table 1 The mixture began transparent
The mixture turned yellow- it gradually went from a pale yellow to a dark yellow
The mixture turned brown after being dark yellow
The time taken was based on which combination of volumes was used Observations The purpose of this lab is to derive a rate expression and calculate the value of the rate constant. Purpose The rate of a reaction between two reactants, A and B, can be calculated experimentally. The rate of a reaction will be proportional to the concentration of A raised to a power and also to the concentration of B raised to a power. The rate of a reaction can be expressed as rate= k[A]^x[B]^y . K is the constant of proportionality and is known as the rate constant. X is known as the order of the reaction with respect to A and y is known as the order of reaction with respect to B. The overall order of the reaction is x + y. The order of the reaction and the rate expression can only be determined experimentally.
