摘要
Certain elements can remain stable in the metastable state during period of reaction under consideration. The composition of reaction product formed under the existence of metastable species might deviate appreciably from that formed under the existence of stable species alone. Activated carbon and gaseous ammonia might be considered as such metastable species that lead to reaction product composition being away from the equilibrium under certain conditions. Experimental evidences giving support to the existence of influences of these metastable species on reaction product compositions are reviewed and conditions fulfilled in order to extract metastability of these species are discussed. © 1990.
