1. Examine your tables. Use Table 1 to find the order for HCl. You are looking for a whole number. You have three possibilities; choose the one that most closely fits your data:

1. If the rate is unchanged when the concentration of HCl changes, then the order for HCl = 0.
2. If the rate doubles when [HCl] doubles, and the rate triples when the [HCl] triples, then the order for HCl = 1.
3. If the rate increases by a factor of four when [HCl] doubles, and the rate increases by a factor of nine when [HCl] triples, then the order for HCl = 2.

I think it would be b. the rate doubles when HCl doubles, but I don't think the rate quite triples when HCl triples. The order would be HCl= 1. Is this correct and could you explain this so I understand it.
