O QUE SIGNIFICA FUGACITY EM INGLÊS
Fugacidade
Na termodinâmica química, a fugacidade de um gás real é uma pressão efetiva que substitui a verdadeira pressão mecânica em cálculos precisos de equilíbrio químico. É igual à pressão de um gás ideal que possui o mesmo potencial químico que o gás real. Por exemplo, o gás nitrogênio a 0 ° C e a pressão de uma fugacidade de. Isto significa que o potencial químico do nitrogênio real a uma pressão de 100 atm é menor do que se o nitrogênio fosse um gás ideal; o valor do potencial químico é o que o nitrogênio como gás ideal teria a uma pressão de 97,03 atm. As fugações são determinadas experimentalmente ou estimadas a partir de vários modelos, como um gás Van der Waals que está mais próximo da realidade do que um gás ideal. A pressão ideal do gás e a fugacidade estão relacionadas através do coeficiente de fugacidade adimensional. Para o nitrogênio a 100 atm, o coeficiente de fugacidade é de 97,03 atm / 100 atm = 0,9703. Para um gás ideal, a fugacidade e a pressão são iguais, assim é 1. A contribuição da não-orientação para o potencial químico de um gás real é igual à RT ln. Novamente para o nitrogênio a 100 atm, o potencial químico é μ = μid + RT ln 0.
definição de fugacity no dicionário inglês
A definição de fugacidade no dicionário também é chamada: tendência de escape, propriedade de um gás, relacionada à sua pressão parcial, que expressa sua tendência a escapar ou expandir, dada por d = dμ / RT, onde μ é o potencial químico, R a constante de gás, e T a temperatura termodinâmica f. Outra definição de fugacidade é o estado ou a qualidade de ser fugaz.
