As the temperature increases the molecules gets more kinetic energy so increases the reaction rate.
Generally increasing the temperature and concentration the reaction rate is higher.
It depends on the acidity level, and the oxygen and moisture content. (Also the type of food.)
The three main factors that affect reaction rates are the concentration of reactants, temperature, and the presence of a catalyst. Increasing the concentration of reactants or temperature generally speeds up reactions, while catalysts can increase reaction rates by providing an alternate reaction pathway with lower activation energy.
The acidity of the liquid in the beaker likely changed due to the addition of an acid or a base, which would alter its pH level. If an acid was added, the pH would decrease, indicating increased acidity. Conversely, if a base was added, the pH would increase, resulting in decreased acidity. Additionally, factors such as temperature or dilution could also affect the acidity of the solution.
Examples: concentration of reactants, temperature, pressure, stirring etc.
Without additional information, it is not possible to determine which beaker contains acidic water and which contains basic water based solely on their temperatures. The acidity or basicity of water is determined by its pH level, not its temperature. pH testing would be needed to determine the acidity or basicity of the water in each beaker.
Some different factors that affect the rates of chemical reactions include whether or not a catalyst is present, the concentration of the reactants, temperature of the reactants, & pressure in the case of gas phase reactions.
The level of acidity
high acidity
Warmer temperature seems to help setting time in many adhesives, and definitely gives epoxies more strength.
the temperature and the humidity, whether you are ill, eg illnesses which affect the acidity of your blood etc.
Temperature plays a significant role on pH measurement. This is a well-know fact for most users of pH test equipment. However, the temperature affects not only your sensor but also your sample. All solutions will change their pH value with temperature. This is a result of the shifting of the chemical equilibrium of the components, mainly of dissociation.
