Help me please

1. The phase diagram of an alloy compromised of components A and B is shown below. For this problem, we are going to keep
the temperature constant at 2000°C (isotherm shown in red). Then, we are going to gradually change the composition of the alloy
from 0 wt% B to 100 wt% B.
Draw your lines neatly. Don't forget units!

a) At what alloy composition will the first solid phase form?
b) What is the composition of this first solid?
c) What phase(s) is/are present in equilibrium at Co = 35 wt% B?
d) What is/are the composition(s) of the phase(s) for an alloy composition of 35 wt% B?
e) Calculate the amount of the phase(s) for an alloy composition of 35 wt% B.
