¿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.

How many moles of oxygen will occupy a volume of 2.5 liters at 1.2 atm
Citrus2011 [14]

<u>We are given:</u><u>_______________________________________________</u>

Volume of Gas (V) = 2.5L

Pressure (P) = 1.2 atm

Temperature (T) = 25°C  OR 25+273 = 298 K

Universal Gravitational Constant (R) = 0.0821

<u>Solving for number of moles:</u><u>___________________________________</u>

From the Ideal Gas Equation,

PV = nRT

(1.2)(2.5) = n(0.0821)(298)           [plugging the given values]

n = [(1.2)(2.5)] / [0.0821*298]

n = 300 / [298*8.21]

n = 0.12 moles

Hence, there are 0.12 moles of Oxygen in 2.5L of 1.2 atm gas when the temperature is 25°C
