<span>The question says, in biochemical reactions, enzymes acts as catalyst causing the............. The correct option is A. The minimum energy that must be overcome before a chemical reaction occur is activation energy. Enzymes act as catalyst to lower the activation energy so that the biochemical reaction can occur. </span>

a. For the reaction 2H2 + 02→ 2H20, how many moles of water can be produced from 6.0 mol of oxygen? 2.0 mol b. 6.0 mol 12 mol d.

pickupchik [31]

Explanation:

from the equation 1 mole of O2 will give 2 moles of H2O then 6.0 moles of O2 will give x

6.0*2 moles/ 1 mole

= 12 moles

this implies that, 6.0 moles of O2 will give = 12 moles of water

Which of the following processes have a ?S > 0?

Ne4ueva [31]

Answer: Cesium chloride dissolves in pure water has $\Delta S$ > 0.

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

$\Delta S$ is positive when randomness increases and $\Delta S$ is negative when randomness decreases.

a) $2HCl(g)\rightarrow H_2(g)+Cl_2(l)$

As 2 moles of gas are converting to 1 mole of gas and 1 mole of liquid, the randomness decreases and hence $\Delta S$ is negative.

b) $2NH_3(g)+CO_2(g)\rightarrow NH_2CONH_2(aq)+H_2O(l)$

As gas molecules are converting into aqueous and liquid form, the randomness decreases and hence $\Delta S$ is negative.

c) lithium fluoride forms from its elements: $2Li+F_2\rightarrow 2LiF$

As elements are combining to form a compound, the randomness decreases and hence $\Delta S$ is negative.

d) Cesium chloride dissolves in pure water : $CaCl_2(s)\rightarrow Ca^{2+}(aq)+2Cl^-(aq)$

As compound is dissociating into ions, the randomness increases and hence $\Delta S$ is positive.
