Answer: D) By decreasing the activation energy of a reaction

A catalyst is a substance that speed up the rate of chemical reaction without affecting the product of the reaction. They only affect the rate of reaction not the yield of reaction.

Catalyst provide an alternative reaction pathway that has lower activation energy  than that of uncatalysed reaction. It increases the frequency of collision and because of these greater collision which lowers the activation energy of the reaction.

Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2. In order to calculate the acceleration of the boat we first have to identify the suited formula for acceleration in this scenario.

Hence, a = vf – vi / t. Vi = 15 m/s Vf = 45 m/s T = 6 seconds  

Solution:
A = 45 m/s – 15m/s / 6s
A = 5m/s^2

The average distance across an ocean is 16,000 km.Two continents on either side of the ocean are con-verging at a rate of 10 cm/
solmaris [256]
The average distance is 16,000 km
Converging rate is  10 cm/year
1 km = 100,000 cm
 = 16,000 × 100,000/10 cm/year
= 160,000,000 years
It will then take 160 Million years to collide.
