какой объем аммиака может окислиться на катализаторе , если для этого используется воздух объемом 56 л

Ответы

Автор ответа: eldorado7

4NH3+O2 -> 4NO+6H2O

содержание кислорода в воздухе 20,95% об.

обьем кислорода 56*0,2095=11,732 л

M( NH3 )=14+3=17 г/моль

M( O2 )= 16*2=32 г/моль

находим количество кислорода 11,732/22,4= 0,524 моль

находим объем аммиака 0,524*4*22,4=46,95 л
