Locate and classify any critical points. (Round your numerical answers to three decimal places. Order your answers from smallest to largest w.) h(w, z) = 0.8w2 + 1.923-4.5wz (w, z, h(w, z)) saddle point (w, z, h(w, z)) relative minimum

Imagine a reaction that results in a change in both volume and temperature, as shown in the diagram below. What is the sign of the work being done and the sign of the enthalpy change involved in this reaction? w = + and delta H = + w = + and delta H = - w = - and delta H = + w = - and delta H = -
