¿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.

Given the reaction 2CO + O2 = 2CO2, what is the minimum number if moles of O2 required to produce one mole of CO2?
Aliun [14]

Answer:

0.5 moles of O₂

Explanation:

See the stoichiometry of the reaction:

2CO + O₂ → 2CO₂

2 moles of carbon monoxide need 1 mol of oxygen to react in order to produce 2 moles of carbon dioxide.

If I want to produce 1 mol of CO₂, I just need the half of O₂.

You will see in this rule of three. Ratio is 2:1

2 moles of CO₂ are produced by 1 mol of O₂        (Stoichiometry - reaction)

1 mol of CO₂ will be produced by ( 1 . 1) / 2 = 0.5 moles
