The phrase "a decrease in reactant" is correct and usable in written English.
It can be used in scientific contexts, particularly in chemistry, to describe a reduction in the amount of a reactant involved in a chemical reaction.
Example: "The experiment showed a decrease in reactant concentration over time, indicating that the reaction was proceeding as expected."
Alternatives: "a reduction in reactant" or "a decline in reactant".
We concluded that a decrease in DOPE in reactant samples was due to modification with an alkyne group.
If all droplets coalesce to some extent, we observe a decrease in particle size with increasing reactant concentration depicting a precipitation process dominated by homogeneous nucleation.
The criterion for such a composite but unitary reaction to proceed is simply that there is overall a decrease in free energy in going from reactants to products.
The experimental and numerical results reveal a sharp increase of up to 300% in the dissolution flux, accompanied by a decrease in the convection onset time, when the reactant concentration-ratio approaches the stoichiometric value.
The value of ( Delta S_{text{ads}}^{o} ) is negative, which implies that a decrease in disordering takes place on going from reactants to the metal adsorbed species reaction complex [55].
The negative values of ΔS* for [PAMTOI] and [MMTOI] imply that the activated complex in the rate-determining step represents an association rather than a dissociation step, indicating that a decrease in disordering takes place on going from reactants to the activated complex [25, 26].
The negative values of entropies (∆S*) implied that the activated complex in the rate determining step represented an association rather than dissociation step meaning that a decrease in disorder took place on going from reactants to the activated complex [42, 43].
Upon illumination (indicated by the thick arrow at the top of the figure) fragments of reaction products are observed to desorb followed by a decrease in the signal due to surface depletion of the reactant.
On the other hand, steric effects lead to a destabilization of the reactant L2PdMe2 complexes but not the transition structures, which results in a decrease in the barriers to reductive elimination compared to the smaller phosphine ligands.
We surmise that a decrease in the downstream products (inositol phosphates and free inositol) or an increase in the upstream reactants (inositol polyphosphates) may lead to transcriptional changes within the cell that result in glycolytic impairment and/or a decrease in cellular LPA levels.
