What is the rate of change of ClF3 concentration in the reaction Cl2(g)+3F2(g)→2ClF3(g) if the rate of change of Cl2 concentration is -0.035 M/s?
The rate of change of Cl2 concentration with respect to time (Δ[Cl2]/Δt) is given as -0.035 M/s. Since the stoichiometric coefficient of Cl2 is 1, this means that the concentration of Cl2 is decreasing at a rate of 0.035 M/s. According to the stoichiometry of the reaction, the rate of change of ClF3 concentration with respect to time (Δ[ClF3]/Δt) is twice the rate of change of Cl2 concentration. Therefore, Δ[ClF3]/Δt = 2 * (-0.035 M/s) = -0.07 M/s. In summary, the rate of change of ClF3 concentration with respect to time is -0.07 M/s, indicating that the concentration of ClF3 is decreasing at a rate of 0.07 M/s.
Understanding the Rate of Change in Chemical Reaction Concentration
Rate of Change Calculation:
The given reaction Cl2(g) + 3F2(g) → 2ClF3(g) involves the consumption of Cl2 and the production of ClF3. The stoichiometric coefficient of Cl2 is 1, while the stoichiometric coefficient of ClF3 is 2. This means that for every 1 mole of Cl2 consumed, 2 moles of ClF3 are produced.
The rate of change of Cl2 concentration with respect to time is -0.035 M/s, indicating a decrease in the concentration of Cl2. As per the stoichiometry of the reaction, the rate of change of ClF3 concentration is twice the rate of change of Cl2 concentration. Therefore, the rate of change of ClF3 concentration (Δ[ClF3]/Δt) is calculated as -0.07 M/s.
Interpretation:
The negative sign in the rate of change values indicates a decrease in concentration over time. In this chemical reaction, the concentration of ClF3 is decreasing at a rate of 0.07 M/s. This information sheds light on the kinetics of the reaction and how concentrations of reactants and products evolve during the reaction process.
In conclusion, the rate of change of ClF3 concentration in the given reaction is determined based on the stoichiometry and the known rate of change of Cl2 concentration. By understanding these rate calculations, we gain insights into the dynamics of chemical reactions and the shifts in concentrations that occur over time.
