# rate of reaction

HideShow resource information
• Rate Of Reacton
• rate of reaction: the amount of product made in a period of time (e.g. - g/s [grams per second])
• reactions are usually fast and they slow down as the reactions are used up
• the rate of a reaction (shown in a graph) can be worked out from the gradient of a graph
• the gradient of the graph is: gradient = y/x
• the limiting react is the reactant not in excess that gets used up by the end of the reaction
• reactions occur when particles collide together, the higher the rate of reaction the high the amount of successful collisions
• therefore if the number of reacting particles of one reactant is limited, the number of collisions by particles of that reactant is limited also
• therefore if the number of reacting particles of one reactant is limited, the number of collisions by particles of that reactant is limited also
