At 25∘c, the decomposition of dinitrogen pentoxide, n2o5(g), into no2(g) and o2(g) follows first-order kinetics with k=3.4×10−5 s−1. a sample of n2o5 with an initial pressure of 760 torr decomposes at 25∘c until its partial pressure is 650 torr. how much time (in seconds) has elapsed? at 25, the decomposition of dinitrogen pentoxide, (g), into (g) and (g) follows first-order kinetics with . a sample of with an initial pressure of 760 decomposes at 25 until its partial pressure is 650 . how much time (in seconds) has elapsed? 5.3×10−6 2000 4600 34,000 190,000

Explanation:

For a first order reaction the rate of reaction just depends on the concentration of one specie [B] and it’s expressed as:

If we have an ideal gas in an isothermal (T=constant) and isocoric (v=constant) process.

PV=nRT we can say that P = n so we can express the reaction order as a function of the Partial pressure of one component.  

Integrating we get:

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.
