Which factor effects the rate of a reaction but is not consumed during the course of the reaction?

The correct answer is a catalyst.

Explanation:

Catalysts are substances that can be added to a reaction to increase the reaction rate without being consumed in the process.

They generally work by reducing the energy of the transition state and thus decreasing the activation energy or changing the mechanism of the reaction. This also changes the nature (and energy) of the transition state. Biochemical processes, such as glucose oxidation, rely heavily on enzymes, proteins that act as catalysts.

Other common types of catalysts are acid-base catalysts and heterogeneous or surface catalysts.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
