An increase in temperature by $10\,^{\circ}C$,generally increases the rate of a reaction by .......... times.

The specific rate constant of a $1^{st}$ order reaction depends on the

Which of the following statements is true about the equilibrium constant and rate constant of a single-step chemical reaction?

Which one of the following given graphs represents the variation of rate constant $(k)$ with temperature $(T)$ for an endothermic reaction?

According to the collision theory of chemical reactions:

If the activation energy of a reaction is $80.9 \, kJ \, mol^{-1}$,the fraction of molecules at $700 \, K$,having enough energy to react to form products is $e^{-x}$. The value of $x$ is ....... . (Rounded off to the nearest integer) $[$Use $R = 8.31 \, J \, K^{-1} \, mol^{-1}]$
