Question: Exercise - Lever rule = > b - m a d - a L b A mixture of A 3 0 % + B 7

Exercise

-

Lever rule

= > \frac{b - m a d - a L}{b}

A mixture of

A 30 % + B 70 %

is cooled from

1400 C

to cross the liquidous line, where we see crystal B start to form. When the mixture is cooled further to the temperature of the red line, how much Crystal B forms from

100 k g

of the mixture? What's the composition of the melt at the temperature?

Exercise - Lever rule =>b-mad-aLb A mixture of A30%+B70% is cooled
