The Gibbs free energy of a mixture of solid A and B ($\alpha$ phase) is given as $\Delta G_{mix} = 10,000 X_A X_B + RT(X_A \ln X_A + X_B \ln X_B)$ (a) When $\Delta H$ is positive, phase separation can occur. The composition range where phase separation occurs is defined by the common tangent rule. Derive an expression for the relationship between $T$ and $X_B$ that defines the composition and temperature range where phase separation occurs. Hint: assume the $\Delta H_{mix}$ versus composition curve is symmetrical in this case. (b) Plot the phase diagram T (y-axis) versus $X_B$ (x-axis) over the temperature range from 300 K < T < 1000 K. (c) Calculate the critical temperature below which a miscibility gap forms.

The income elasticity of demand measures: how responsive your demand for a good is to changes in your income. how responsive the demand for one good is to price changes in another good. the total amount you receive from buyers, which equals price times quantity. the ratio of percent change in the quantity supplied to the percent change in the price.

Part 1: The derivative at a specific point Use the definition of the derivative to compute the derivative of $f(x) = 1 - 9x^2$ at the specific point $x = 0$. Evaluate the limit by using algebra to simplify the difference quotient (in first answer box) and then evaluating the limit (in the second answer box). $f'(0) = \lim_{h \to 0} \left( \frac{f(0 + h) - f(0)}{h} \right) = \lim_{h \to 0} \left( -9h \right) = $ Part 2: The derivative at another specific point
