The rate of a reaction doubles when its temperature changes from $300\text{K}$ to $310\text{K}$. Activation energy of such a reaction will be ($R=8.314{\text{J K}}^{-1}{\text{mol}}^{-1}$ and $\log 2=0.301$):

Synthesis of each molecule of glucose in photosynthesis involves:

Which of the following complex species is not expected to exhibit optical isomerism?

A piston filled with $0.04\text{mol}$ of an ideal gas expands reversibly from $50.0\text{mL}$ to $375\text{mL}$ at a constant temperature of $37.00^{\circ }\text{C}$. As it does so, it absorbs $208\text{J}$ of heat. The values of $q$ and $w$ for the process will be ($R=8.314\text{J/mol K}$):

A gaseous hydrocarbon gives upon combustion $0.72\text{g}$ of water and $3.08\text{g}$ of ${\text{CO}}_2$. The empirical formula of the hydrocarbon is:
