mean lifetime sentence in Hindi

Examples

1. If the Arrhenius equation is valid over the wide temperature range in this case and the mean lifetime at room temperature, 4.3x10-11 s ( multiplicative inverse of the number given by 87.102.86.73 ) is correct, the mean lifetime is about 1 s at 88 K with a 25 kJ / mol inversion barrier; 1 hour at 71 K; at the boiling point of nitrogen it's 114 seconds, and at the boiling point of neon it's far longer than the age of the universe ( 2.6x10 33 s ).
