Question

В емкости смешали натрий и йод. Смесь нагрели. Через 13 с концентрация йодида натрия в емкости стало равной 0,5 моль/л. Определите среднюю скорость образования йодида натрия.

Answer 1

Ответ:

Объяснение:

ΔC=0.5 моль/л

Δt=13 с

Wср(накопления продукта NaI)=ΔC/Δt=0.5/13=0.0385 моль/л*с

Answer 2

Calculating the Average Rate of Sodium Iodide Formation

To calculate the average rate of sodium iodide formation, we can use the given information about the change in concentration of sodium iodide over time. The concentration of sodium iodide in the container increased to 0.5 mol/L after 13 seconds of heating.

The formula for average rate of reaction is:

Average Rate = (Change in concentration)/(Change in time)

Using the given concentration change and time, we can calculate the average rate of sodium iodide formation.

Calculation

The change in concentration of sodium iodide is 0.5 mol/L, and the change in time is 13 seconds.

Average Rate = (0.5 mol/L) / (13 seconds)

Average Rate = 0.0385 mol/(L·s)

So, the average rate of sodium iodide formation is 0.0385 mol/(L·s).
