41. Solution to Chemistry Problem

1. Based on the experimental data on the crystallization onset temperatures T (Table 2.1) of a two-component system containing w% of substance A, construct a phase diagram of the system.
Content A, w%, 0 10.0 20.0 30.0 40.0 50.0 64.0 66.7 71.0 75.3 82.2 100
T, K 1349 1308 1236 1123 1019 1103 1200 1203 1193 1177 1247 1397
Assuming that the total mass of the system is 1 kg, calculate from the diagram the composition and ratio of phases at temperature T and the total content of component A in the system w% (Table 2.2)
Indicator T, K 1100
A, w% 85
