It is found that a gas undergoes a first-order decomposition reaction. If the rate constant for this reaction is 8.1 x 10-2 /min
, how long will it take for the concentration of the gas to change from an initial concentration of .1M to 1.0 x 10-2 M?
1 answer:
Answer:
28.43 min
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given that:
The rate constant, k = min⁻¹
Initial concentration = 0.1 M
Final concentration = M
Time = ?
Applying in the above equation, we get that:-

Answer:
lower energy that helps the balance
Answer:
Explanation:
1 Al = 26.98 AMU
3 Br = 239.7 AMU
AlBr3 = 266.69 AMU
Al = (26.98)/(266.69) = 10.1%
Br3 = (239.7)/(266.69) = 89.9%
