Answer: Option (A) is the correct answer.
Explanation:
A catalyst is a substance which helps in increasing the rate of a reaction without itself getting consumed in the reaction.
A catalyst lowers the activation energy of a reaction so that reactant molecules with less energy can easily participate into the chemical reaction and thus, product formation becomes faster.
Thus, we can conclude that adding a catalyst to the reaction would reduce the activation energy of a chemical reaction.

Answer:
Energy produced by the chip =10,460 Joules.
Explanation:
The specific heat of water is one calorie/gram ° C = 4.186 joules/gram ° C, which is higher than any other common substance. As a result, water plays a very important role in regulating temperature. The specific heat per gram for water is much greater than that of a metal, as described in the water-metal example. Replace the mass (m), the temperature change (ΔT), and the specific heat (c) of the solution in the equation Q = c x m x ΔT, where Q is the heat absorbed by the solution. For specific heat of water we goes as given in the question 4,184 J/kg°C
Q =4184×0.5×(25-20)
=10,460 Joules.
Thus heat gained by water (Q)= Energy produced by the chip =10,460 Joules.
