RATES OF REACTION

RATES OF REACTION. Rates of Reaction. The rate of a chemical reaction is the speed at which the reaction occurs (i.e. speed at which the reactants are used or products are produced). Rate can be measured by the: 1) change in mass of reactants or products . 2) change in pH

Rates of Reaction

Rates of Reaction. Rates of Reaction. Reactions occur because there are successful collisions between reactant particles, i.e. they collide in the correct direction and with enough energy. If they do not have enough energy, they are dud collisions .

RATES OF REACTION

RATES OF REACTION. (CHAPTER 6). Rate of Reaction: speed at which a chemical reaction occurs  usually expressed as the change in concentration per unit of time. Product being formed or reactant being consumed. Measurements can include mass, colour, conductivity, volume, and pressure.

Rates of Reaction

Rates of Reaction. 18.1. The heat given off by the corrosion reaction of an iron-magnesium alloy with salt water can produce a hot meal. The rate of reaction is increased by adding salt water, so heat is produced rapidly. You will learn some ways in which the rate of a reaction can be increased.
