`A(g) rightarrow 2B(g) + C(g)` is a first order reaction . The initial pressure of the system was found to be `800 mm Hg` which increased to `1600 mm Hg` after `10 min` . The total pressure of the system after `30`min will be ____mm Hg .(Nearest integer)

The reaction 2N_(2)O_(5)(g)rarr4NO_(2)(g)+O_(2)(g) follows first order kinetics. The pressure of a vessel containing only N_(2)O_(5) was found to increase from 50 mm Hg to 87.5 mm Hg in 30 mim. The pressure exerted by the gases after 60 min. will be (Assume temperature remains constant):

For the first order reaction A(g) rarr 2B(g) + C(g) , the initial presuure is P_(A) = 90 m Hg , the pressure after 10 minutes is found to be 180 mm Hg . The rate constant of the reaction is

At 373 k, the following reaction A(g)rarr2B(g)+C(g) is found to be of first order. Starting with pure A, the total pressure at the end of 10 minutes was 176 mm Hg and after a long time when A was completely dissociated, it was 270 mm Hf. The pressure of A at the end of 10 minutes was
