We know that ΔG₀ = – RT lnK_c, where ΔG₀ is the standard Gibbs free energy, R is universal gas constant, T is the temperature and K_C is equilibrium constant; substituting ΔG₀ as -2502 J/mol, we get -2502 J/mol = -8.314J mol^–1K^–1 × T ln2 = 2502 J/mol = T = 2502/2.502 = 100 k.

If the value of Gibbs free energy is greater than the zero that means, -ΔG₀/RT is negative and that e^-ΔG₀/RT is greater than 1, so the K is greater than 1 this means the reaction is nonspontaneous and proceeds in the forward direction.

Is the value of Gibbs free energy for a reaction is 20 J/mol, that means it is positive, -ΔG₀/RT is negative and that e^-ΔG₀/RT is greater than 1, so the K is greater than 1 this means the reaction is nonspontaneous.

The distance between A and B is 10 units. The distance between B and C is 5 units. Hence, the total distance is 15 units. The total time taken is 100 s. Average speed = total distance/total time taken = 15/100 = 0.15 units/s.

The distance between A and B is 13 units. The distance between B and C is 10 units. Hence, the total distance is 23 units. The total time taken is 20 s. Average speed = total distance/total time taken = 23/20 = 1.15 units/s.

From the given options, the only motion that can possibly have a uniformly accelerated motion in a plane is that of a particle. In circular motion the direction of the acceleration keeps changing and in a pendulum and in a spring, both the magnitude and directions keep changing.

Apart from the genomic DNA present inside the nucleus, the mitochondria possesses its own genetic material in the form of a single circular DNA molecule. This DNA codes for some mitochondrial proteins.

Chromoplasts impart colours to the different cells of a plant such as yellow colour of a flower or a fruit. Elaioplasts store oils and fats, amyloplasts store starch and aleuroplasts store proteins.

Chloroplasts are plastids containing the green pigment chlorophyll, which is necessary to trap sunlight to carry out the process of photosynthesis. Chlamydomonas has only one chloroplast per cell.

Chloroplasts are plastids which contain the green pigment chlorophyll. The stroma is the ground substance of the chloroplast. It contains enzymes which are required for the synthesis of carbohydrates and proteins.
