¿Cómo afectaría la velocidad de una reacción si se enfría lentamente la mezcla de los reactivos? AYUDA
hodyreva [135]

Answer:

La velocidad de reacción se ralentizará más rápidamente de lo habitual.

Explanation:

Dado que los factores que influyen en la velocidad de una reacción química son;

1) Temperatura de la mezcla reaccionante

2) Concentración (para líquidos) y área superficial de presión (para gases) (para sólidos) de los reactivos

3) catalizador

4) Reactantes naturaleza

5) Orientación de las moléculas reactivas reactivas

Tenemos que, específicamente, disminuir la temperatura del reactivo disminuye la probabilidad de que las moléculas de los reactivos involucrados en colisiones dentro de la mezcla tengan suficiente energía (que es igual o mayor que la energía de activación, Ea) para que la reacción se complete . Es decir, habrá una disminución en las colisiones efectivas (colisiones que provocan una reacción) y la reacción se ralentizará.

Dado que la velocidad de reacción se ralentiza con el tiempo, los reactivos de enfriamiento lento ralentizan rápidamente la reacción.

Archy [21]

Answer : The chemical symbol for the element that results from this process is, (Ar) for argon.

Explanation :

Electron capture : In this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. Simply, a proton and an electron combines together to form a neutron. Mass number does not change in this process.

_Z^A\textrm{X}+_{-1}^0\textrm{e}\rightarrow _{Z-1}^A\textrm{Y}

The equation for the given reaction is,

_{19}^{40}\textrm{K}+_{-1}^0\textrm{e}\rightarrow _{18}^{40}\textrm{Ar}

Thus, the chemical symbol for the element that results from this process is, argon (Ar).
