The decomposition of sulfuryl chloride (so2cl2) is a first-order process. the rate constant for the decomposition at 660 k is 4.5 ✕ 10−2 s-1. (a) if we begin with an initial so2cl2 pressure of 430. torr, what is the pressure of this substance after 70. s?

18.43 Torr is the pressure of this substance after 70seconds.

Explanation:

Rate of the reaction ,k=

Integrated rate equation for first order kinetics in gas phase is given as:

p= pressure of the gas at given time t.

= Initial pressure of the gas

When, t = 70 sec

p = 18.43 Torr

18.43 Torr is the pressure of this substance after 70 seconds.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

the answer is a for sure mark brainliest i had got this right on usatestprep
