The given reaction is exothermic,
X + Y ----> XY + Heat
Heat is a product. So, if the temperature is increased, the equilibrium is shifted towards the reactants. So, the <u>[X] increases</u>.
It should be watts. <span>A </span>watt<span> is the number of </span>joules generated per second. <span>A kilocalorie is 4,184 </span>joules<span>, the amount of energy that will heat 1 kilogram of water by 1 degree </span>Celsius<span>. </span>
A proton is the same as an H+ ion, and Arrhenius acids are the ones that release H+ in solution, so the answer is A
