What else can I help you with?
What causes the reaction rate to decreases as the reaction progresses?
The concentration of the reactants decreases.
What causes the equilibrium to shift to the left?
The equilibrium shifts to the left when there is an increase in the concentration of reactants or a decrease in the concentration of products. This can also happen when the temperature is decreased in an exothermic reaction.
What causes pressure changes of reactants to affect the reaction rate?
The frequency of collisions is changed.
What causes the reaction rate to decrease as the reaction progresses?
The concentration of the reactants decreases.
What factors change the rate of chemical reaction?
The rate of reaction is affected by temperature,concentration,particle size, and the use of a catalyst. 1. Temperature (An increase in temp causes there to be an increase in kinetic energy. This results in an increase in collision frequency and therefore, an increase in rate of reaction.) 2. Concentration (An increase in concentration increases the probability of collisions. This causes there to be an increase in rate of reaction as well.) 3. Particle Size (A decrease in particle size results increases the surface area. This increases the #of collisions which also increases the rate of reaction.) 4. Use of a Catalyst (A catalyst increases the chance of particles meeting and lowers the activation energy. This results in an increase in the rate of reaction.)

What causes the reaction rate to decreases as the reaction progresses?
The concentration of the reactants decreases.
What happens to the equilibrium concentration of reactants when the volume of the reaction system is decreased and why?
When the volume of the reaction system is decreased, the equilibrium will shift towards the side of the reaction with fewer moles of gas to relieve the pressure. This causes the concentration of reactants to increase in order to establish a new equilibrium.
What causes pressure changes of reactants to affect reaction rate?
The frequency of collisions is changed.
What causes the concentration of reaction to affect the reaction rates?
It increases the number of collisions at the right orientation.
What causes the equilibrium to shift to the left?
The equilibrium shifts to the left when there is an increase in the concentration of reactants or a decrease in the concentration of products. This can also happen when the temperature is decreased in an exothermic reaction.

What causes the reaction rate to decrease as the reaction progresses?
The concentration of the reactants decreases.
Why the rate of reaction does not remain constant?
The rate of a chemical reaction does not remain constant because it depends on various factors, such as the concentration of reactants, temperature, and the presence of catalysts. As the reaction progresses, the concentration of reactants decreases, leading to a reduction in the rate of reaction according to the rate laws. Additionally, changes in temperature can alter the kinetic energy of particles, influencing how frequently they collide and react. Therefore, the dynamic nature of these factors causes the rate of reaction to vary over time.
What do you understand by energy of activation?
it's energy that causes starting of reaction between reactants

Are substances formed in a chemical reaction called reactants?
no, that's what causes the reaction to occur, it is actually called a product.
