TOPIC 1: RATES AND CHEMICAL EQUILIBRIUM QUESTION 1: (Taken from the DoE Physical Sciences Feb-March Paper 2 2009) Antacids are used to relieve indigestion. Indigestion is the condition when the stomach produces too much acid resulting in an uncomfortable and painful feeling. A certain antacid tablet dissolves in water and reacts with the acid in the stomach to release carbon dioxide gas. 1.1 Name the type of chemical reaction that explains why antacids bring relief from indigestion

Introduction The solubility product constant‚ Ksp‚ is a particular type of equilibrium constant. The equilibrium is formed when an ionic solid dissolves in water to form a saturated solution. The equilibrium exists between the aqueous ions and the undissolved solid. A saturated solution contains the maximum concentration of ions of the substance that can dissolve at the solution’s temperature. The equilibrium equation showing the ionic solid lead chloride dissolving in water is: PbCl2(s)

Demand‚ Supply and Market Equilibrium Every market has a demand side and a supply side and where these two forces are in balance it is said that the markets are at equilibrium. The Demand Schedule: The Demand side can be represented by law of downward sloping demand curve. When the price of commodity is raised (ad other things held constant)‚ buyers tend to buy less of the commodity. Similarly when the price is lowered‚ other things being constant‚ quantity demanded increases. The above

Oligopoly An oligopoly is an intermediate market structure between the extremes of perfect competition and monopoly. Oligopoly firms might compete (noncooperative oligopoly) or cooperate (cooperative oligopoly) in the marketplace. Whereas firms in an oligopoly are price makers‚ their control over the price is determined by the level of coordination among them. The distinguishing characteristic of an oligopoly is that there are a few mutually interdependent firms that produce either identical products

Torques equilibrium‚ and center of gravity Introduction Torque is a quantitative measure of the tendency of a force to cause or change the rotational motion of a rigid body. A torque is the result of force acting at a distance from an axis of rotation. An essential thing to keep in mind is that the magnitude of the torque is equal to the product of the forces perpendicular distance and magnitude. Theory The magnitude of the torque (t) is found from the product of the force F and

forward and backward reactions are the same‚ it is said to be in a state of dynamic equilibrium. The position of this dynamic equilibrium can be moved forward by changing the conditions the reaction is done in. This follows Le Chatelier’s Principle which says changes to a system in equilibrium will move it in an opposite direction.
