Q. At 300 K, the half life of a sample of a gaseous compound initially at 1 atm is 100 sec. When the initial pressure at same temperature is 0.5 atm the half life is 50 sec, the order of the reaction is x. What is the value of x?

NO and $B r_{2}$ at initial partial pressure of 98.4 and 41.3 torr, respectively were allowed to react at 300K. At equilibrium the total pressure was 110.5 torr. Calculate the value of KP for the following reaction at 300K.

$2 N O (g) + B r_{2} (g) ⇌ 2 N O B r (g)$
