What factors increase the rate of a chemical reaction? 2. When is equilibrium established in a reversible reaction? 3. How does a system at equilibrium respond to the addition of more reactant 4. How does a system at equilibrium respond to the addition of more product? 5. In Part C, we look at the following reaction: Felp)+SCN ) rece(a)

Answer 1

Answer 1

Rate of chemical reaction increases:

• By increasing temperature to some extent.
• By adding catalyst.
• By using finely powdered reactants
• By allowing reactants to be close enough to react.

Answer 2

Equilibrium is establish when concentration of product and reactants remain constant, though reaction

Answer 3

Addition of reactant shifts reaction towards products (forwards)

Answer 4

Addition of products shifts reaction towards products I.e
