- When [A] is doubled, the rate doubles; when [B] is doubled, the rate quadruples; when [C] is doubled, the rate does not change. How would the rate change if the concentration of A and C are doubled when the concentration of B is tripled? A(g) + B(g) + C(g) => products A) The rate decreases by a factor of 4. B) The rate decreases by a factor of 2. C) The rate increases by a factor of 2. D) The rate increases by a factor of 4. E) The rate increases by a factor of 8. F) The rate increases by a factor of 16. G) The rate increase by a factor of 18.
