Anna was asked to identify and explain if the equation
CO2 (g) → CO2 (I) was an endothermic or exothermic
reaction. However she got it wrong. What is her error
and what should the answer have been?
Anna's statement: The equation is an endothermic
reaction because the energy is released from gaseous
CO2 to the surroundings to become liquidCO2
causing the molecules to speed up.

(a) Explain the meaning of the sentence:“The velocity laws of reactions are empirical” (b) It can be determined that the velocity law of a generic reaction A +B→Pév = k[A]x[B]y. Plot on a graph the variation of [A] and [P] with time, and explain why v= d[P]/dt = -d[A]/dt.

- The maximum rate I at which oxygen molecules can be consumed by a bacterium or radius R in a lake where the concentration of oxygen is co = 0.2 mole m³ increases with the first power of R. We might expect the oxygen consumption, however, to increase roughly with an organism's volume. Together, this statements imply an upper limit to the size of a bacterium: If R gets too large, the bacterium would literally suffocate. The actual metabolic activity of a bacterium is about 0.02 mole kg-' sl. What limit do you then get on the size R of a bacterium? Compare to the size of a real bacteria. Can you think of some way for a bacterium to evade this limit?arrow_forwardNatural gas consists primarily of methane, CH4(g).(a) Write a balanced chemical equation for the completecombustion of methane to produce CO2(g) as the onlycarbon-containing product.
