In a closed reaction vessel, pressure "p(atm)" is found to vary with time "t(s)" according to the following linearized equation: p = a (1/t3) + b what are the units of a? a. a = atm. s3 b. a = 1/s3 c. a = atm d. a = atm/s3

The units of a are A. a = atm.s³.

Explanation:

In the equation P = a (1/t³) + b, both terms "a (1/t³)" and "b" must have units of pressure, e.g., atm. Regarding units, we can say:

We can solve this for a:

If we replace P and t with proper units, then

a = P.t³ = atm.s³

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
