- What is the maximum number of phases that can be in mutual equilibrium in a four-component system ( The maximum number of phases occur when the F = 0).arrow_forwardMake a concrete example of a linear dynamical system that observes a stable equilibrium, unstable equilibrium and no equilibrium or fixed point respectively.arrow_forwardFor the reaction H2(g) + Br2(g) 2HBr(g), Kc = 81.4 at 385ºC. If [H2] = [Br2] = [HBr] = 1.6 × 10–2 M at 385ºC, which one of the following is correct? Group of answer choices The reaction is at equilibrium already. The reaction will proceed in the forward direction because K > 1. The reaction will proceed in the reverse direction to reach equilibrium because Q < K. The reaction will proceed in the forward direction to reach equilibrium.arrow_forward

If 0.850 M each of N2 and O2 are initially present in a 3.00-L vessel, calculate the equilibrium concentrations of NO, N2, and O2.arrow_forwardIt is also referred to as mechanical equilibrium because it is often applied in mechanical context rather than a chemical context. a) Dynamic Equilibrium b) Static Equilibrium c) Phase d) Molecular forcesarrow_forward
- STATE WHETHER The statements are TRUE OR FALSE please specify 1. Consider stirring a cake mix with an electric mixer. This is an adiabatic process that is irreversible because the energy stored within the system cannot be spontaneously released in a manner to cause the mass of the system to turn the paddle wheel in the opposite direction to do work on the surroundings. ( TRUE OR FALSE)? 2. When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region. Hence, a non-quasi-equilibrium compression process requires a larger work input than the corresponding quasi-equilibrium one. ( T/F) 3. A reversible expansion or compression process cannot involve unrestrained expansion or sudden compression, and thus it is non-quasi-equilibrium. (T/F) 4. A quasi-equilibrium expansion or compression process involves…arrow_forwardIf a certain system has one component, at what number of phases will the formula of degrees of freedom starts to become invalid?arrow_forwardThermodynamics mechanical engineering question: An equimolar mixture of CO and O₂ reacts to form an equilibrium mixture of CO₂, CO and O₂ at 3000 K, 5 atm.
