Chemistry Carousel 3

• half equations show which electrons transfer at which electrode.
• Increasing the surface area, increases the rate of reaction due to more particles having the ability to collide meaning more frequent collisions. (more kinetic energy).
• Collision theory means that chemical reactions only occur when particles collide with sufficient energy.
• Reaction profile is a diagram showing whether the reactants have more or less energy than the products.
• To measure the rate of reaction on a graph, one would need to draw a tangent to the curve and then calculate the gradient.
• Temperature, surface area of a solid, concentration in reactants, pressure in gases, catalysts all affect the rate of reaction.
• Increasing the temperature, increases the rate of reaction due to an increase in speed of particles, meaning more frequent collisions. Increase the number of particles which have activation energy, meaning more collisions result in a reaction.
• For a simple ionic liquid, metal is produced at the cathode.
• For a simple ionic liquid, non-metal is produced at the anode.
• In the electrolysis of an ionic solution, oxygen will be produced if the non-metal is not a halogen.
• Increasing the surface area on the rate of reaction, will increase the rate.
• Increasing the pressure of gases on the rate of reaction, will increase the rate.
• Measuring the quantity of a reactant or a product is in grams or cm3 (cubed)
• The formula for mean rate of reaction (in terms of products) is quantity of reactant produced formed / time taken.
