Answer:
Particles can only react when they collide. If you heat a substance, the particles move faster and so collide more frequently. That will speed up the rate of reaction. ... The rate of reaction will probably have doubled for that increase in temperature - in other words, an increase of about 100%.

2) 
3) 
4) 
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
1) 
Here, 
is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.
2) 
Here, 
is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.
3) 
Here, 
is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.
4) 
Here, 
is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.
