What is dynamic equilibrium? Why is it called dynamic?

Consider the following reaction at equilibrium. What effect will increasing the temperature have on the system? FeзО4(s) + CO(g) — 3 FeO(s) + СO2(9) AH°= +35.9 kJ The equilibrium constant will decrease. No effect will be observed. The concentration of CO2 (g) will increase.. The concentration of CO (g) will increase. The reaction will shift to the right in the direction of products. о

Hydrogen and fluorine react to form hydrogen fluoride, like this: H,(g)+F2(g) → 2 HF (g) The reaction is exothermic. Suppose a mixture of H,, F, and HF has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. 圖 do perturbation change in composition shift in equilibrium O to the right The temperature is raised. The pressure of H2 will O to the left go up.
