Answer:
Explanation:
For example, the energy released in burning 1 mol of octane, a component of gasoline, is about 5000 kJ.
The energy released in the fission of 1 mol of uranium-235 is
about 1.5 × 10¹⁰ kJ .
The ratio is

Answer: D. The number of molecules having Er or greater doubles.
Explanation: As the temperature increases from 20°C to 30°C, the number of molecules with maximum energy decreases, but the number of effective collisions which result into the formation of product doubles.
This is due to doubling of molecules which possess energy equal to or greater than which means now double number of molecules will be able to cross the energy barrier and hence the formation of product increases and hence the rate increases to double.
