Number of Correct statement(s) regarding the following first-order reaction is/are2N2O5g→4NO2g+O2g

According to first – order reaction, −dN2O5/dt=kN2O5. The half life can be found as t=2.303klogaa−x Where, a = 100 and a - x = 100 - 99.6 = 0.4.Then half-life period for first-order reaction decreases with increase in temperature  t12=In2k=0.693k    If the reaction completes to 99.6% completion then, t99.6=2.303klog1000.4=2.303k2.4=8×0.693k=8t1/2.half life period of first order reaction do not depend on initial concentration.
