Answer:
I dont know how to take a picture so I will just tell you the answer. The answer is no.
Explanation:
Hope this helps. :) :D

Answer:
74 % major, 26 % minor product
Explanation:
The total area under the peaks is
85 units + 30 units = 115 units
Answer:
228 s
Explanation:
In a zero order reaction, the formula for the half life is given as;
t1/2 = [A]o / 2k
To obtain the rate constant k, we have to use;
[A] = [A]o - kt
kt = [A]o - [A]
From the question;
it takes 342 seconds for 75% of a hypothetical reactant to decompose.
We have;
t = 324
[A] = 25
[A]o = 100
Upon solving for k we have;
kt = [A]o - [A]
k = ( [A]o - [A] ) / t
k = (100 - 25 ) / 342
k = 75 / 342 = 0.2193
Solving for t1/2;
t1/2 = [A]o / 2k
t1/2 = 100 / 2(0.2193)
t1/2 = 100 / 0.4386 = 228 s
Answer:
a) 1.8 kJ
Explanation:
ΔG=-RtLnK
Just input the data into the equation to gives us the result, in Joules.
ΔG=-8.314*(25+273.15)*ln(0.48)
ΔG=1819,37 J
But there is only 2 significant figures, so we express it as 
or 1.8 kJ
