Two flasks `A` and `B` have equal volume. `A` is maintained at `300 K` and `B` at `600 K`. While `A` contains `H_(2)` gas, `B` has an equal mass of `CH_(4)` gas. Assuming ideal behaviours for both the gases, answer the following: Flask with greater molar kinetic energyA. `A`B. `B`C. Both `A` and `B`D. None |

Answer» Since `KE per mole=(3)/(2)RT`, `KE per mole of A=(3)/(2)RT_(A)` `KE per mole of B=(3)/(2)RT_(B)` Hence `(KE per mole of A)/(KE per mole of B)=(T_(A))/(T_(B))=(300)/(600)=(1)/(2)` `:. KE per mole of Alt KE per mole of B` |
