Methyl ethyl ether (A) and diborane, B¿Ho (B), form a compound that melts congruently at 133 K. The system exhibits two eutectics, one at 25 mol per cent Band 123 K and a second at 90 mol per cent Band 104 K The melting points of pure A and Bare 131 K and 110 K, respectively. (a) Sketch the phase diagram for this system Assume negligible solid-solid solubility. (b) Label all the regions appropriately (c) On the phase diagram indicate a triple point with a point and label it T (d) On the phase diagram indicate a critical point with a point and label it C. (e) Using the Gibbs phase rule determine the number of degrees of freedom from the number of components and the number of phases for the equilibrium reaction: K,CO3(s) = K;0(s) + CO:(g).
