Temp and rate of reaction graph
Webtemperature Summary Some chemical reactions are very fast (e.g. combustion of gasoline), and others very slow (e.g. rusting). For various practical reasons, it is interesting to understand why a reaction is fast or slow. It requires knowledge of the parameters influencing the reaction rate. WebTemperature and Rate Chemical reactions typically require collisions between reactant species. These reactant collisions must be of proper orientation and sufficient energy in order to result in product formation. Collision theory provides a simple but effective explanation for the effect of many experimental parameters on reaction rates.

WebGraph 1 shows the relationship between change in temperature and the rate of reaction. The trend shows that as the temperature of the HCl increases, so does the rate of reaction. This is a polynomial relationship, which implies that the rate of reaction increases exponentially in relation to the increase in temperature.
