Answer:
Higher frequency
Explanation:
We can imagine a chemical bond between two atoms as if it were two balls connected by a spring.
According to Hooke's Law, the stretching frequency f is

where µ is the reduced mass of the system

The strength of the bond is analogous to k, the force constant of the spring. Then,

Thus, the stronger the bond, the greater the frequency of vibration.
Answer:
Explanation:
An element with atomic number 18 is a noble gas.
The element with atomic number 19 will have one extra electron so it can donate one electron or shed one electron to attain noble gas configuration .
It tends to shed one electron to become positively charged ion . Hence they are electro-positive elements .
Similarly the element with atomic number 17 will have one short electron so it can gain one electron to attain noble gas configuration .
They tend to gain one electron to become negatively charged ion . Hence they are electro-negative elements . They have high electronegativity .
Answer:
Rate = 1.321M/s[H₂CO₃]¹ ; k = 1.32M/s
