Answer:
A catalyst increases the rate of reaction by decreasing activation energy. ... Enzymes are highly substrate specific and catalyze reactions by providing an alternate pathway of lower activation energy.

The entropy of a system can be calculated by the ratio of the total heat in the system and the temperature. Entropy is a measure used in thermodynamics to approximate the degree of disorder in a system. From the equation for entropy, we can calculate the enthalpy as follows:
S = H / T
109.0 J / mol K = H / 373.15 K
H = 40673.35 J / mol
Son átomos que tienen el mismo número atómico, pero diferente masa atómica. Es decir, contienen el mismo número de protones pero difieren en el número de neutrones. Como ejemplo, tendríamos el Hidrógeno y sus 3 isótopos, el Protio, el Deuterio y el Tritio.
Answer:
1 mole is equal to 1 moles Potassium, or 39.0983 grams.
39.0983g X 4 = 156.3932
so 4 moles are in 156 grams of Potassium
