Which hypothesis is supported by the data if the experimental error is minimized and the results consistently show a decrease in reaction time with increased temperature?
A
The reaction rate decreases with temperature.
B
The reaction rate fluctuates randomly with temperature.
C
The reaction rate is independent of temperature.
D
The reaction rate increases with temperature.
Verified step by step guidance1
Understand the relationship between temperature and reaction rate: According to the Arrhenius equation, an increase in temperature generally leads to an increase in the reaction rate because molecules have more kinetic energy, leading to more frequent and effective collisions.
Identify the hypothesis that aligns with the observed data: The data shows a decrease in reaction time with increased temperature, which implies that the reaction is happening faster as the temperature rises.
Evaluate each hypothesis: The first hypothesis suggests a decrease in reaction rate with temperature, which contradicts the data. The second hypothesis suggests random fluctuations, which is not supported by consistent data. The third hypothesis suggests no change with temperature, which is also inconsistent with the data.
Select the hypothesis that matches the data: The correct hypothesis is that the reaction rate increases with temperature, as this is consistent with the observed decrease in reaction time.
Conclude with the supported hypothesis: Based on the data and understanding of chemical kinetics, the hypothesis that the reaction rate increases with temperature is supported.
