1.) consider the processes or reactions, indicate which side of the reaction will have the greatest entropy and explain why. (4 pts) a. co2 (s)co2 (g) b. caco3 ( cao (s) + co2 (g) c. 2 no2 (g) -> n204 (g) d. h20 (1) at 25 °c heated to 52 °c

A. Right side since CO2 has has more entropy than solid CO2

B. Right side since gaseous CO2 is present on right side

C. Left side since more no of gaseous molecules om left side

D. Right side since on heating of water at 52C starts boiling hence more entropy for vapour.

Explanation:

Generally entropy is the measurement of randomness and follows the order gas>liquid>solid

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.

explanation:

thats not the answer u need to drop the right one bruh
