Lowers the activation energy, providing a faster pathway.

: Activation Energy (minimum energy required for a reaction to occur). chemical kinetics short notes pdf free download

Most reactions speed up as temperature increases. Lowers the activation energy, providing a faster pathway

): A proportionality constant specific to a reaction at a given temperature. Molecularity Definition Sum of powers in the rate law. Number of reacting species colliding. Values Can be 0, fraction, or integer. Always a whole number (1, 2, 3). Determination Experimental only. Theoretical (from mechanism). 6. Integrated Rate Equations (Quick Formulas) Zero Order: | Half-life ( t1/2t sub 1 / 2 end-sub First Order: | Half-life ( t1/2t sub 1 / 2 end-sub Lowers the activation energy

Generally, higher concentration = higher rate.

This explains the effect of temperature on the rate constant:
