factors affecting the rate of reaction

temperature, concentration, surface area and catalysts

affect of increasing temperature

particles get more kinetic energy, leading to more collisions per second

an ________ in temperature, increases the number of particles with an energy high enough for a collision

increase

affect of increasing concentration

there are more particles in the same volume, meaning a higher chance of a successful collision

by increasing the ___________, you are increasing the number of particles in the same volume

concentration

affect of increasing the surface area

higher number of particles are exposed to the other reactant and can therefore react faster

because more particles of the solid reactant are exposed, there will be more ________ collisions, leading to an increase in the rate of reaction

frequent

affect of a catalyst

provides an alternative reaction pathway with a lower activation energy, as a result the reaction rate increases

catalysts _____ consumed in the reaction and so they are shown in a written reaction above the arrow

aren’t
