Adjust temperature and concentration to see how particle speed and density control how fast a reaction really happens.
A + B → C | Purple + Teal collide to make Gold
Change conditions and observe the rate.
Higher temperature = faster particles = more frequent, harder collisions.
More particles in the same space = more chances to collide.
A higher barrier means only the fastest collisions succeed.
Reaction rate (successful collisions per second) over the last 60 seconds.
Raising temperature gives particles more kinetic energy. They move faster and collide more often — but more importantly, a greater share of those collisions now has enough energy to overcome the activation barrier and react.
Higher concentration means more particles in the same volume. With more A and B molecules around, the odds of a collision go up proportionally. Double the concentration, double the collision frequency.
