Which of these statements is not true about chemical reaction rates?
Sliva [168]
I think it is A. The reaction rates can change.
I think we all know that B. and C. are incorrect, but I took a science lesson about this and it specifically said that on a graph of a rate, a curved line is NOT constant, meaning it is possible to not be constant.

The system by which organisms get and give energy is
Debora [2.8K]

The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

The data in the table describes the properties of three substances. Based on the data, identify whether each substance is ionic,
GuDViN [60]
Substance A is ionic because in molten and aqueous solution conduct electricity and dissolves in water. This is because it dissociate in ions and ion conduct electicity and dissolve in polar molecules (water). Ionic bond is very strong (high melting point).
Substance B non polar covalent, because it is not dissolve in polar molecules and has weak intermolecular forces (low melting point).
Substance C is polar covalent because polar molecules have stronger intermolecular forces than non-polar and higher melting points.

For the reaction below, an analysis of an equilibrium mixture isperformed at a certain temperature.
DerKrebs [107]

Answer:

k = 3.2 x 10¹¹

Explanation:

The equilbrium taking place is:

  • N₂(g) + 3Cl₂(g) ↔ 2NCl₃(g)

And the expression for the equilbrium constant <em>k</em> is

  • k = [NCl₃]² / ( [N₂] * [Cl₂]³)

We are given all the required data from the problem, so now we <u>solve for k</u>:

  • k = (1.9x10⁻¹)² / ( (1.4x10⁻³) * (4.3x10⁻⁴)³ )
  • k = 3.2 x 10¹¹

After 62.0 min, 33.0% of a compound has decomposed. What is the half-life of this reaction assuming first-order kinetics?
nikdorinn [45]
Half life is determined using the equation expressed as:

A = Ao e^-kt

First, we need to find for the value k.

A = .67Ao = Ao e<span>^-k(33 min)
k = 0.0121

The half-life is then calculated as follows:
</span>A = .5Ao = Ao e<span>^-0.0121(t)
</span><span>t = 57.28 min

</span>
