All of the following are factors that affect the rate of a reaction except _____ A) the concentration of the reactants. B) prese
Dmitry_Shevchenko [17]

The rate of a reaction is not affected by C) the magnitude of the equilibrium constant.

<h3>What is the rate of a reaction?</h3>

The rate of a reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.

Let's consider which of the following factors affect the rate of a reaction.

  • A) the concentration of the reactants. YES. The relationship between the concentrations of the reactants and the reaction rate depends on the reaction orders.
  • B) presence of a catalyst. YES. Positive catalysts increase the reaction rate whereas negative catalysts decrease it.
  • C) the magnitude of the equilibrium constant. NO. The equilibrium constant does not affect the reaction rate.
  • D) the temperature of the reaction. YES. Usually, the higher the temperature, the faster the reaction.
  • E) the surface area of the solid reactants. YES. The more surface area exposed to react, the faster the reaction.

The rate of a reaction is not affected by C) the magnitude of the equilibrium constant.

Convert<br> 12 x 1025 kg/mL to fg/cm3
Anna35 [415]

Answer:

1.2x10^{38}\frac{fg}{cm^3}

Explanation:

Hello there!

In this case, for such unit conversion we need to realize that 1 kg is equal to 1000 g, 1 g is equal to 1x10⁹ and 1 mL equals 1 cm³, therefore we apply:

12x10^{25}kg*\frac{1000g}{1kg} *\frac{1x10^9fg}{1g} *\frac{1mL}{1cm^3} \\\\1.2x10^{38}\frac{fg}{cm^3}

Best regards!

I have to get this done fast
anastassius [24]

Answer:

Animals would, instead of getting energy from the food that they eat like meat or plants, they would get their energy from the sun like plants do.

Explanation:

Because like what the paper says, Chloroplasts help with the photosynthesis, which is the process in which a plant gains its energy.

Do pure substances have the same chemical and physical properties
