You would use a stopwatch. Hope this helps :D
Answer:
Negative
Explanation:
For a solution to form, the change in Gibbs free energy must be negative for dissolving. When a solute dissolves in a saturated solution, ΔH(enthalpy change) is negative and ΔS(entropy change) is positive, giving rise to a large negative ΔG(change in gibbs free energy) and a very high solubility.

Answer:
Kinetic Rate Laws. The rate of the crystal violet/NaOH reaction is given by the following generalized rate law. Rate = k [OHG] [CV]. (1) x y. 25. 30.
The reaction was carried out by varying the concentrations of [CV] within the range 1.00 × 10-5 M-7.00 × 10-5 M at 298 K and fixed [NaOH]o=1.67 × 10-3 M and μ=0.085 M (KNO3). The reaction is dependent on the [CV] as observed rate constant (kobs) increases with increase in [CV] as shown in Table 1.
Explanation:
to calculate the room temperature rate constant for the reaction. BACKGROUND. Reaction Chemistry. Chemical kinetics is the study of reaction rates.
