According to le chatelier's principle, by increasing the temperature of the system shown below, the equilibrium will shift to the right (towards products).a b imported asset heat ab. is that true?

The statement for the said principle is "If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change." If the reaction gives off energy or is exothermic then the statement will be false however when the reaction absorbs energy or is endothermic then the statement will be true.

They can measure  the amount of energy gained or lost

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.
