The authors of this article would like to bring attention to the following correction and modifications.

There was a typo on the values of β reported to fit the rate coefficients to a Arrhenius-Kooji equation (Eq. 5 of the original paper). This parameter appears with the wrong sign in table 2, in the abstract, in the Reaction rates section and in the Conclusions.

The figures presented in the manuscript are correct, and this typo does not change the discussion. This correction is mainly significant in case other authors may use the Arrhenius-Kooji parameters on astrochemical models.

We take the opportunity to redo the fit for the N + PH → P + NH reaction, to avoid the previous very small negative value of gamma (associated with the activation energy), and set it to zero. The change in the curve is negligible, as seen in the updated figure below. All updated values are shown in Table 1 of this correction, which replaces table 2 of the original manuscript.
