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.
Answer:
=42
Step-by-step explanation:
The expression 8×7×9×49×3 can be written in its simplest factor form as follows.
8=2³
49=7²
9=3²
Thus the expression becomes:2³×7×3²×7²×3
Combine the indices to the same base.
2³×3³×7³
Finding the cube root involves dividing the index by three.
Thus ∛(2³×3³×7³)= 2×3×7
=42
34/100
= 0.34
3 tenths, 4 hundreths

Answer:
x = 3
Step-by-step explanation:
Multiply both sides by the exponent 2/3.
Solve for the exponent.
Add 8 to both sides.
Divide 8 into both sides.
