A few factors influence the rate of reaction, including :

<em>Temperature</em>. Most reactions increase in rate as temperature increases; most reactions slow down as temperature decreases.

<em>Concentrations of the reactant</em>. Raising the concentration of a substance will increase the speed of the reaction; lowering the concentration of a substance will decrease the speed of the reaction. The limiting reactant is the reactant that is completely used up in a reaction. When this is completely used up, the reaction will stop.

<em>Catalysts</em>. These are substances that speed up the rate of the reaction by lowering the activation energy. If a catalyst is added, the rate of reactions will increase. If a catalyst is removed, the rate of reactions will decrease. Enzymes are biological catalysts used in living things to speed up internal reactions.

<em>Inhibitors</em>. These are substances that slow down the rate of a reaction. If an inhibitor is added to a reaction, its rate will decrease. If an inhibitor is removed from a reaction, its rate will increase.

Thus, the right answer is B. Lowering the concentration of the reactants

At 1 atm, how much energy is required to heat 39.0 g of h2o(s at –24.0 °c to h2o(g at 121.0 °c?
earnstyle [38]
Q = mcΔt, q = energy [J] m = mass (of water) [g]; c = specific heat capacity of water [J g⁻¹ K⁻¹/°C⁻¹]; Δt = change in temperature [K/°C]
Δt = 121 - -24 = 145
q = 39 × 4.18 × 145
q = 23637.9 J

¿Qué elemento tiene el mismo número de órbitas que el Hidrógeno? ¿Por qué? ¿Tienen propiedades similares, por qué?
Aliun [14]

What element has the same number of orbits as Hydrogen? Why? Do they have similar properties, why?

Answer:

Helium

Explanation:

Helium has the same number of orbitals as hydrogen because they belong to the same period on the periodic table.

Periods are the horizontal arrangement of elements. Elements in the same period are known to have the same number of electronic shell or orbitals.

In period 1 where we have just Hydrogen and Helium, the number of orbitals is 1.

 

For properties of a specie, elements in the same group which are the vertical arrangement of elements have the same properties. Since both Hydrogen and helium are in different groups, their properties differ.
