absolute zero
At equilibrium, the net rate of the reaction is zero, meaning that the rate of the forward reaction equals the rate of the reverse reaction. This balance results in no net change in the concentrations of the reactants and products over time. Although individual molecular events continue to occur, the overall concentrations remain constant.
Molecular clocks are tools used to estimate the timing of evolutionary events based on the mutation rates of genes over time. While they primarily focus on genetic changes, the concept of reaction rates in molecular biology relates to how quickly these changes can occur under specific environmental conditions. In essence, both molecular clocks and reaction rates reflect dynamic processes at the molecular level, where reaction rates can influence the frequency of mutations and, consequently, the reliability of molecular clocks in tracking evolutionary timelines.
Molecules are not in random motion when a substance is at absolute zero, the lowest possible temperature at which molecular motion ceases. At this point, molecular movement only exists due to the zero-point energy, preventing complete immobilization.
In a first-order chemical reaction, the velocity of the reaction is proportional to the concentration of the reactant. In contrast, in a zero-order reaction, the velocity of the reaction is independent of the concentration of the reactant and remains constant over time.
"absolute zero" or 0 degrees Kelvin.
absolute zero
The rate law for a zero-order reaction is rate k, where k is the rate constant. In a zero-order reaction, the rate of the reaction is independent of the concentration of the reactants.
Cohesive reaction is the process where an adhesive goes through a molecular change. This molecular change creates a new material or substance.
A chemical reaction alters molecular composition.

No. Molecular oxygen is a reactant in a combustion reaction.

The temperature scale that places zero at the point where all atomic and molecular motion ceases is called the Kelvin scale. On the Kelvin scale, this point is defined as absolute zero, which is equivalent to 0 Kelvin (0K).
