Based on the trend from the graph, the reaction time would have been 32.5 seconds.
<h3>What is the trend in the graph?</h3>
A trend is a general pattern which an observation follows based on previous observations and occurrences.
The reaction time is the time it take for a chemical reaction to occur.
Reaction time is also a measure of reaction rate. The shorter the reaction time, the faster the reaction rate and vice versa.
Based on the trend from the graph, the reaction time would have been 32.5 seconds.
In conclusion, reaction time is a measure of reaction rate.

Answer:
All exothermic reactions _c.release energy____
Explanation:
Exothermic reactions are those that give off energy, for example in the form of heat in combustion (it has a negative enthalpy variation, the energy of the products being less than the energy of the reagents)
