4. The decomposition of SO2Cl2 is a first-order reaction: SO2Cl2 (g) → SO2 (g) + Cl2 (g). A 1.24 × 10–3 M sample of SO2Cl2 drops to 3.1 × 10−4 M after 495 min. a. What is the value of the rate constant, k?

b. What is the half-life for this reaction?

5. Gaseous azomethane, C2H6N2, decomposes according to the following equation:

C2H6N2 (g) → N2 (g) + C2H6 (g)

A 2.00 g sample if azomethane is placed in a flask at 425°C and the amount that

remain is recorded in the table shown.

a. Provide evidence for why this process is first-order.

b. Find the value for the rate constant, k. Include units.

c. After how much time will only 0.050 g remain?

6. Consider the decomposition of nitrogen dioxide, NO2: 2 NO2(g) → 2 NO(g) + O2(g)

a. Find the rate law for this reaction.

b. Find the value of the rate constant k. Include units.

c. In trial 2, how long will it take for [NO2] to reach 0.002 M?

the movement of aircraft through clouds can even cause lightning strikes. a single lightning event is a "flash", which is a complex, multi-stage explosively ejected.

explanation:

and the person below goggled it.

mark as brainliest

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
