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.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
