1. Which statement concerning a catalyst is TRUE:
Catalyst raises the activation energy Enzymes are not catalysts Catalyst speeds up a reaction In a reaction the catalyst is usually consumed Catalyst increased the cost of production

2. For a 2nd order reaction, if the concentration is doubled, the reaction rate will:
triple quadruple stay the same double none of the above

3. A + B + C --> products is:
