The number of collisions made by a single molecule with other molecules per `cm^(3)` per second. Is `Z_(1)`. At constant temperature by how much will `Z_(1)` change if the pressure is doubled in the vessel.A. Increase `2` timesB. Decrease `2` timesC. Increase `0.5` timesD. Decrease `0.5` times |

Answer» `Z_(1)=sqrt(2) pi sigma^(2)overline(c ) N^(*)` (`overline(c ) =` average velocity) (`N^(*)=` Number of molecules per `cm^(3)`) `Z_(1) prop P` (when `T` is constant) `Z_(1) prop (1)/(sqrt(T))` (when `P` is constant) `Z_(1) prop sqrt(T)` (when volume is constant) |
