Abstract: The Intrinsic Reaction Coordinate (IRC) for the titled reaction was traced by means of HF/ 6-31G.The reaction activation energy is 105.9 kJ/mol(PUMP3/6-31Genergy barrier+ HF/6-31Gzero-point energy correction).The reaction rate constants calculated by CVTand tunneling effects are obtained by small-curvature method(SCSA.G).

Key words: Reaction rate constant, IRC curvature, IRC coupling constant, Acetylene
