The collision theory states that when two or more particles have sufficient energy and orientation, the collision will be successful in producing a reaction. There are many ways to increase the rate of a ...

It provides an alternative reaction pathway with a lower activation energy. However, it does not lower the activation energy for the 'normal' reaction without a catalyst.

The relative formula mass (Mr) of a compound is the sum of the relative atomic masses of the atoms in the numbers shown in the formula.

Relative formula mass (Mr) of CaCO3 = 40+12+(3x16)=100.

First, it depends on whether the forward reaction is exothermic or endothermic. Lets use the formation of ammonia as an example: N2 + 3H2 <-> 2NH3. The forward reaction is exothermic, so it releases...

In a dynamic equilibrium the rate of the forward reaction is the same as the rate of the reverse reaction and there is no overall change in the amount of each product.
