Question

(vi) State the fa
State the factors which affect the speed (or rate) of a reaction. Describe any
two factors with examples.​

Answer 1

Answer:

Factors Affecting Reaction Rate:

# Nature of reactants

# Concentration

# Temperature

# Pressure

# Catalyst

# Surface area

Explanation:

# Temperature:

Most of reaction go faster at higher temperature. Because provide heat energy to reactants to break more chemical bonds between atoms.

Ex: Caco3 reacts with HCI is relatively slow. when this mixture is heated the reaction rate increases.

# Pressure:

If the reactants are gases, increasing their pressure increases the reaction rate. On increasing their pressure the particles are comes closer and colloid frequently.
