Question

B (rate is dependent on reactants, not products)

why not the others?
A - forces reaction L → R
C - more energy = faster
D - could be a reactant and influence the outcome
E - speeds reactions by lowering activation energy

**rate depends on concentration and states of reactants, temperature and presence of a catalyst

Answer 1

The rate of a chemical reaction depends on factors such as the nature of the substances, the state of subdivision of the reactants, temperature, concentration, and the presence of a catalyst.

Step-by-step explanation:

The rate of a chemical reaction depends on several factors:

1. The chemical nature of the substances involved: Different reactants may have different reaction rates under the same conditions.
2. The state of subdivision of the reactants: Reactions generally occur faster when the reactants are in smaller particles.
3. The temperature of the reactants: Increasing the temperature generally increases the reaction rate by providing more energy for collisions between molecules.
4. The concentration of the reactants: Higher concentrations generally lead to faster reaction rates because there are more reactant molecules available for collisions.
5. The presence of a catalyst: A catalyst can increase the reaction rate by providing an alternative pathway with a lower activation energy.
