What is the meaning of the statement "less rotational entropy (fewer degrees of freedom )will be lost as the reaction proceeds towards the transition state the smaller negative entropy increases the rate of the reaction"? U DU CILUUUU CO DH L2 achieved by ensuring that the reactants are in the correct orientation as they approach each other. A good example of rate enhancement by this means is pro- vided by the rates of lactone (internal ester) formation in compounds (I)...
2. State which one has a higher entropy (irregularity) value than the two the following choice! Explain your answer. (a) Item 1, CO2 solid samples at -78°C, or item 2, CO2 gas samples at 0°C (b) Item 1, rock sugar, or item 2, the same sugar is dissolved in a cup of tea
3. The amount of entropy generation during a process represents the irreversibilities and is process path-dependent. True or False

For the two degrees of freedom system shown in Figure 4, determine the steady state response of the system due to a sinusoidal force Fi() 10sin10r applied to the mass block whose displacement isn. Given m = 10 kg, k = 1000N rn and the equations of motion of the system are -지 3m 09. For the two degrees of freedom system shown in Figure 4, determine the steady state response of the system due to a sinusoidal force...

3. Consider the equation of motion of a single-degree-of-freedom system: mi + ci + kx = F(1) Derive the condition that leads to divergent oscillations in each of the following cases: (a) when the forcing function is proportional to the displacement, F(t) = F,x(t); when the forcing function is proportional to the velocity, F(t) = Fox(t); and (c) when the forcing function is proportional to the acceleration, F(t) = F,x(t).
