Temperature increases the kinetic energy of the particles, they move quicker, they collide more often, more collisions mean a faster rate of reaction
Increasing concentration means that there are more particles to collide with each other, more collisions per second, the frequency for successful collisions increase
Catalysts provide an alternate reaction pathway at a lower activation energy
Increasing surface area: increases its surface area to volume ratio, so there'll be more frequent collisions and the rate of reaction will be faster
Increasing pressure means that the particles are more compressed, less space for them to move around, frequency of collisions increase, faster rate of reaction
