Anika [276]

Factors that increases reaction rate such as increase in concentration or pressure will reduce reaction time whereas factors that decrease reaction rate such as inhibitors will increase reaction time.

<h3>What are the factors that affect reaction rate?</h3>

Factors that affect reaction rate are those factors which increase or decrease the rate of chemical reaction.

The factors that affect reaction rate include:

  • temperature
  • concentration/pressure
  • catalysts
  • surface area
  • nature of substance

Any factor that increases reaction rate such as increase in concentration or pressure will reduce reaction time whereas factors that decrease reaction rate such as inhibitors will increase reaction time.

The digit that would have to be estimated in reading this instrument would be the nearest:
wariber [46]

Answer:

The least count of vernier calipers is 0.01 g.

(B) is correct option.

Explanation:

Given that,

The digit that would have to be estimated in reading this instrument,

According to figure,

We need to calculate the pitch

Using formula of pitch

pitch=\dfrac{distance\ moved}{Number\ of\ complete\ rotation}

Put the value into the formula

pitch=\dfrac{1}{10}

pitch=0.1\ g

We need to calculate the least count of vernier calipers

Using formula of least count

Least\ count=\dfrac{pitch}{number\ of\ vernier\ scale\ division}

Put the value into the formula

Least\ count=\dfrac{0.1}{10}

Least count = 0.01\ g

Hence, The least count of vernier calipers is 0.01 g.

(B) is correct option.
