Rate Laws and Temperature

[Meigan Wu 2E]

How do rate laws relate to temperature in regards to equations?

[Kristen Kim 2K]

The constant k in the differential rate law depends on temperature and activation energy.
RATE = k[R]^n

[Jake Gordon 1A]

I agree, I think the calculated k only applies at the given temperature. If you increase temperature the molecules have more Kinetic energy and this will alter the probability that they run into each other with proper orientation and sufficent energy and therefore k must be a different value to have the law correspond with experimental values at the new temperature.

k once calculated is only for that temperature, which is why we have the Arrhenius equation to help calculate the new k when temperature changes

[Lorena Zhang 4E]

Depending on what reaction's happening, the change of temperature would affect the rate of reaction. Therefore, we can conclude that since the concentration stays the same, k has to change.
