Answer:
A Pareto chart, named after an Italian economist, combines a bar chart with a line graph. The bar chart is different from a histogram in more than one way. For example, the vertical bars need not touch one another as per a histogram
Explanation:
Answer:
The correct option is a , c
Explanation:
Generally the fringe spacing is mathematically defined as

Where y is the fringe spacing
m is the order of the fringe
is the wavelength
D is the distance between the slit and the screen
d is the distance between the slit
Now in order to increase the fringe spacing can do the following
- Increase the wavelength
- increase the distance from the slit to the screen
- Decrease the distance between the slit
The following action would increase the fringe spacing because the from the question these parameters are directly proportional to the fringe spacing
I dont think so. It also probably matters what type of str it is
By definition we have to:
LOG (k2 / k1)=(-Ea/R)*(1/T1-1/T2)
Where,
k1 = 0.0117 s-1
K2 = 0.689 s-1
T1 = 400.0 k
T2 = 450.0 k
R is the ideal gas constant
R = 8.314 KJ / (Kmol * K)
Substituting
ln (0.0117/0.689)=-Ea/(8.314)*((1/400)-(1/450))
Clearing Ea:
Ea = 122 kJ
answer
<span> the activation energy in kilojoules for this reaction is
