Coefficient Grade 10 SABIS SABIS The number preceding the chemical symbol and indicating the quantity of particles

Effect of changing surface area on rate of reaction: Grade 10 SABIS ​ if one of the reactants is a solid, the more divided or broken it is, the larger is its surface area and the more particles will be in contact with the other reactant. This leads to particles colliding more frequently and so the rate increases.

Electrical Work Grade 10 SABIS ​ Electric work is the energy supplied by an electric current. In thermochemistry, it refers to the energy transfer that occurs during an electrochemical reaction or when electrical energy is used to perform work. To understand electric work, let's consider an everyday example: charging a mobile phone. When you connect your phone to a charger, electrical energy flows from the power source to the phone's battery. This energy transfer allows the battery to store electrical energy, which can later be used to power the phone and perform various tasks. Similarly, when you plug in an electrical device such as a laptop or a blender, electric work is done to power the device and enable its functionality. The electrical energy supplied through the power cord allows the device to operate and perform the desired tasks. In thermochemistry, electric work is involved in various electrochemical processes. For instance, during electrolysis, an electric current is passed through a solution or molten compound, causing a chemical reaction to occur. This reaction is driven by the electric work performed, leading to the separation or deposition of substances. Consider the process of electroplating, where a thin layer of metal is deposited onto an object. By passing an electric current through a solution containing metal ions, the metal ions are reduced and form a solid metal layer on the object's surface. The electrical work is responsible for driving this electrochemical process. Electric work is also crucial in battery technology. When a battery is used to power a device, such as a flashlight or a remote control, electric work is done as the chemical reactions inside the battery generate an electric current. This current supplies the necessary energy for the device to function. In summary, electric work in thermochemistry refers to the energy transfer that occurs during electrochemical reactions or when electrical energy is used to perform work. Examples include charging a mobile phone, operating electrical devices, electrolysis, electroplating, and battery-powered devices. Understanding electric work helps explain the energy transformations involved in various electrochemical processes and the role of electrical energy in powering everyday devices.
