C2h4(g) + h2(g) mc030-1.jpg c2h6(g) which change would likely cause the greatest increase in the rate of the reaction?

The reaction is a hydrogenation reaction of an alkene, and its equation is:
C₂H₄(g) + H₂(g) → C₂H₆(g)
Therefore, this reaction can be sped up just as any other irreversible reaction may have its rate increased, by increasing temperature and pressure to increase the effective collisions of molecules.

Density because it’s holyyy

A) the enthralling of formation for pure element in its standard state is always positivehope this : )
