The answer is the 3rd one
Answer:31.8 °C
Explanation:
Delta T=?
C= .24 cal/g°C
M=612g
Q=1835
Delta T= 1835 cal/(.24cal/g°C)(612g)=12.50°C
Intial temp= 19.3°C
Add intial temp to new temp
12.50+19.3=31.8°C
Answer:
(B) Neutralization...........,
Explanation:-
Neutralisation involves an acid reacting with a base or an alkali, forming a salt and water.
Decreasing the temperature in the reaction vessel keep this reaction from shifting to form more of the product.
As we know that rate of reaction is directly proportional to the concentration of the reactant.
If we increase the concentration of H2 then the rate of reaction increases. So, we keep it constant. Therefore this option is wrong.
By removing the H₂O from the reaction vessel as it almost make no change in the reaction. This can be pursuited the reaction in which product again converted into product.
By increasing the temperature we increases the rate of reaction and equilibrium shift in the forward direction.
Thus, we concluded that by decreasing the temperature in the reaction vessel keep this reaction from shifting to form more of the product.
