kinetics

Just problem one please.

1). A biological reaction follows this equation, S=P, in presence of an enzyme E. Derive the reaction rate expression. 2). Derive the equation for the rate of deposition of Si from Si2H6 using a thermal process at 600C. Si2H6(g)s2SiH2+H2SiH2+XSiHXSiH2X12Si(s)+H2(g) Assume reactions (1) and (2) are very fast
