The activation energy is the amount of energy required to initiate a certain reaction. The activation energy may considered as an "energy barrier" that has to be overcome in order for a reaction to begin. If a reaction has a lower activation energy, then it will occur more easily and at a faster rate than a reaction with a higher activation energy. Therefore, the reason that reaction 1 is faster than reaction 2 is because it has a lower activation energy than reaction 2.
Integer generally means number.
if s = seconds then
2s = 18
solve for s,
18/2 = 7
s = 7 seconds
Answer:
Step-by-step explanation:
Since we're finding the product, we have to multiply:
× 
You can simplify in this stage by using the "butterfly method", and dividing 
by , and 
by , you'd then have:
× 
Multiply the numerators and the denominators to get:
~
If you prefer the longer way, again, multiply:
×
Multiply the numerators and the denominators:
Simplify the fraction by dividing both the numerator and denominator by :
15x+25y=1875
Let
y=95-x
15x+25 (95-x)=1875
Solve for x
15x+2375-25x=1875
15x-25x=1875-2375
-10x=-500
X=500/10
X=50 the number of $15 items
Y=95-50=45 the number of $25 items
