The rate of a chemical reaction is related to:_______

Chemistry
1 answer:
aalyn [17]1 year ago
8 0

The correct answer for this question is activation energy, orientation, and frequency.

The rate of a chemical reaction is directly related to its activation energy because the higher the activation energy the lower is the rate of reaction as we know the reaction only proceed when the reactants have absorbed the enough heat energy to reach the transition state. Thus activation energy determines the rate of reaction.

The orientation of the particles is also very important as we know that the reaction between the two reactants only occur when they collide with proper orientation in time the greater the probability of the collision the greater is the rate of reaction and also the number of collisions also determines the rate of reaction.

The frequency is directly proportional to the rate of chemical reaction as the frequency of the collision increases the rate of the chemical reaction also increases.

Which of the following is a salt that will form from the combination of a strong base with a weak acid?
zaharov [31]

Answer:

A. NaHCO₃

Explanation:

NaHCO₃ ⇒ NaOH + H₂CO₃

NaOH is a strong base and H₂CO₃ is a weak acid. Therefore, NaHCO₃ is a salt of a strong base-weak acid reaction. The salt is basic because carbonic acid (H₂CO₃) is a weak acid so it remains undissociated. So, there is a presence of additional OH⁻ ions that makes the solution basic.

Hope that helps.

How many moles (of molecules or formula units) are in each sample?
Alexus [3.1K]

The number of moles in each sample will be 0.391 moles, 30.7 moles, 0.456 moles, and 1350 moles

<h3>What is the number of moles?</h3>

The number of moles of a substance is the ratio of the mass of the substance to the molar mass.

In other words; mole = mass/molar mass.

Thus:

  • moles of 18.0 g NO_2 = 18.0/46

                                   = 0.391 moles

  • moles of 1.35 kg CO_2 = 1350/44

                                         = 30.7 moles

  • moles of 46.1 g KNO_3 = 46.1/101.1

                                          = 0.456 moles

  • moles of 191.8 kg Na_2SO_4 = 191800/142

                                                 = 1350 moles
