  General 
  Curves 
  for 
  Reactions 
  of 
  Higher 
  Orders. 
  

   Gas-reactions 
  of 
  higher 
  orders 
  are 
  rarely 
  met 
  with 
  (except 
  

   in 
  the 
  case 
  of 
  combustion 
  of 
  many 
  hydrocarbons), 
  therefore

  General 
  curves 
  for 
  

   any 
  particular 
  type 
  of 
  reaction 
  can 
  be 
  obtained 
  by 
  following 
  

   a 
  procedure 
  similar 
  to 
  that 
  used 
  in 
  this
