A student conducts an experiment. He mixes two chemicals in a beaker at 30 ° Celsius. Then, he repeats the experiment at 45 ° Ce
Salsk061 [2.6K]

The most likely conclusion the student will make would be that increasing temperature increases the rate of reaction.

<h3>Effects of temperature on reaction rates</h3>

The rate of reaction of a system is directly proportional to the temperature of the system.

This is because the kinetic energy of the reactant's molecules is increased by increasing the temperature of the system. Thus, reactant molecules collide more and this leads to more reactions.

Thus, increasing the temperature of a system moderately also increases the rate of reaction in the system. Too much increase in temperature, however, can destroy the structures of reactants.
