In a zero-order reaction for every \(10^{\circ} \mathrm{C}\) rise of temperature, the rate is doubled. If the temperature is increased from \(10^{\circ} \mathrm{C}\) to \(100^{\circ} \mathrm{C}\), the rate of the reaction will become
1 64 times
2 512 times
3 265 times
4 128 times
Explanation:
Rate or rate constant doubles for every \(10^{\circ}\) or \(10 \mathrm{~K}\) rise in temperature \(\therefore \dfrac{r_{100}}{r_{10}}=(2)^{9}=512\)

Rate of a reaction
1 decreases with increase in temperature
2 increases with increase in temperature
3 may increase or decrease with increase in temperature
4 does not depend on temperature
Explanation:
The rate of exothermic reaction decreases with the increase in temperature and that of endothermic reaction increases with increase in temperature. Thus, it can be said that rate may increase or decrease with increase in temperature.

The rate of a reaction quadruples when temperature changes from \({\mathrm{27^{\circ} \mathrm{C}}}\) to \({\mathrm{57^{\circ} \mathrm{C}}}\). Calculate the energy of activation. Given \({\mathrm{\mathrm{R}=8.314 \mathrm{JK}^{-1} \mathrm{~mol}^{-1}, \log 4=0.6021}}\)

The rate of a chemical reaction doubles for every \(10^{\circ} \mathrm{C}\) rise of temperature. If the temperature is raised by \(50^{\circ} \mathrm{C}\), the rate of the reaction increases by about
1 24 times
2 64 times
3 10 times
4 32 times
Explanation:
For every \(10^{\circ} \mathrm{C}\) rise of temperature, rate is doubled. Thus, temperature coefficient of the reaction \(=\) 5 When temperature is increased by \(50^{\circ}\), rate becomes \(=2^{(50 / 10)}=2^{5}\) times \(=32\) times
