For a chemical reaction to happen ... In addition, how long a reaction is observed for depends on the rate of reaction. Reactions can vary from being almost instantaneous to taking years to ...

If they collide with enough energy, bonds can break and new bonds can form in a chemical reaction. The reactants just sit there until energy is added with the flame. The added energy is enough to make ...

From explosions to rusting, how rapidly chemical reactions occur is fundamental in many aspects of chemistry in the school laboratory and in society. In this topic you will consider the factors ...

and catalysts can all affect the reaction rate. Reversible reactions - (CCEA) Some chemical reactions are reversible, and may reverse even as they react. This can create a state of dynamic ...

Rate (y axis) against concentration (x axis). The shape of each graph indicates whether the order of reaction for a particular reactant is zero, first or second order. Plot graphs of reaction rate ...

Hydrogen peroxide decomposes on its own into water and oxygen gas. This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate, and the bubbles are full of oxygen ...

Chemical reactions between solid reactants occur at ... mostly products formed at this interface determines the reaction rate. The theory predicts a cause for reaction acceleration: due to the ...
