  2. Le Chatelier's principle - Wikipedia

    en.wikipedia.org/wiki/Le_Chatelier's_principle

    If we were to decrease pressure by increasing volume, the equilibrium of the above reaction will shift to the left, because the reactant side has a greater number of moles than does the product side. The system tries to counteract the decrease in partial pressure of gas molecules by shifting to the side that exerts greater pressure.

  3. Production–possibility frontier - Wikipedia

    en.wikipedia.org/wiki/Production–possibility...

    In microeconomics, a production–possibility frontier (PPF), production possibility curve (PPC), or production possibility boundary (PPB) is a graphical representation showing all the possible options of output for two that can be produced using all factors of production, where the given resources are fully and efficiently utilized per unit time.

  4. Pressure jump - Wikipedia

    en.wikipedia.org/wiki/Pressure_Jump

    The volume change can thus be understood to be the pressure dependency of the change in Gibbs free energy associated with the reaction. When a single step in a reaction is perturbed in a pressure jump experiment, the reaction follows a single exponential decay function with the reciprocal time constant (1/τ) equal to the sum of the forward and ...

  5. Robinson Crusoe economy - Wikipedia

    en.wikipedia.org/wiki/Robinson_Crusoe_economy

    The boundary of the production possibilities set is known as the production-possibility frontier (PPF). [9] This curve measures the feasible outputs that Crusoe can produce, with a fixed technological constraint and given amount of resources. In this case, the resources and technological constraints are Robinson Crusoe's labour. [1]

  6. Van 't Hoff equation - Wikipedia

    en.wikipedia.org/wiki/Van_'t_Hoff_equation

    For a reversible reaction, the equilibrium constant can be measured at a variety of temperatures. This data can be plotted on a graph with ln K eq on the y-axis and ⁠ 1 / T ⁠ on the x axis. The data should have a linear relationship, the equation for which can be found by fitting the data using the linear form of the Van 't Hoff equation

  7. Critical point (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Critical_point...

    The commonly known phases solid, liquid and vapor are separated by phase boundaries, i.e. pressure–temperature combinations where two phases can coexist. At the triple point, all three phases can coexist. However, the liquid–vapor boundary terminates in an endpoint at some critical temperature T c and critical pressure p c. This is the ...

  8. Guns versus butter model - Wikipedia

    en.wikipedia.org/wiki/Guns_versus_butter_model

    A, however, is inside of the PPF and represents a combination of output that is not utilizing all available resources. In macroeconomics, the guns versus butter model is an example of a simple production–possibility frontier. It demonstrates the relationship between a nation's investment in defense and civilian goods.

  9. Rybczynski theorem - Wikipedia

    en.wikipedia.org/wiki/Rybczynski_theorem

    Suppose production occurs initially on the production possibility frontier (PPF) at point A. Suppose there is an increase in the labour endowment. This will cause an outward shift in the labour constraint. The PPF and thus production will shift to point B. Production of clothing, the labour-intensive good, will rise from C 1 to C 2.
