Question

Как измерить скорость реакции 4Al+3Cl2=2AlCl3 если уменьшить концентрации исходных веществ в 2 раза ?

Answer 1

V= k*[Cl2]^3 
УМЕНЬШИТСЯ в 2^3 раза = в 8 раз

Answer 2

Measuring the Reaction Rate of 4Al + 3Cl2 = 2AlCl3

To measure the reaction rate of the chemical equation 4Al + 3Cl2 = 2AlCl3, we can use the concept of the rate of reaction, which is the change in concentration of reactants or products per unit time. When the concentrations of the reactants are reduced by a factor of 2, the reaction rate can be determined using the rate equation.

Rate Equation: The rate equation for the given chemical reaction is typically expressed as:

Rate = k[Al]^m[Cl2]^n

Where: - k is the rate constant - [Al] and [Cl2] are the concentrations of aluminum and chlorine, respectively - m and n are the orders of the reaction with respect to aluminum and chlorine, respectively

Determining the Reaction Order

To determine the orders of the reaction with respect to aluminum and chlorine, experimental data or additional information about the reaction mechanism is required. Without this information, it's not possible to determine the exact values of m and n.

Conclusion

In summary, to measure the reaction rate of 4Al + 3Cl2 = 2AlCl3 when the concentrations of the reactants are reduced by 2 times, the rate equation and the orders of the reaction with respect to aluminum and chlorine need to be known. Without this information, it's not possible to provide a specific numerical value for the reaction rate under the given conditions.
