The answer is correct because observing Carefully, you will notice that the reaction is not a neutralization but a Redox
Reaction between acid and base is exothermic so it has to be A
Cause decrease of temperature in exothermic reaction increase d forward reaction
Option C is correct bcos of the factors affecting the rate of a chemical reaction
with an increase in temp. there's an increase in the reaction rate same as increase in conc
read up for better understanding
yh I think d ans is correct bcos an increase in temperature in endothermic reaction favours d forward reaction and am not sure dis is an exothermic reaction
