To calculate the rate constant for a first-order reaction, you can use the natural logarithm function. Rearrange the integrated rate law for a first-order reaction to solve for the rate constant. In this case, k = ln(2)/(t(1/2)), where t(1/2) is the half-life of the reaction. Given that the reaction is 35.5% complete in 4.90 minutes, you can use this information to find the half-life and subsequently calculate the rate constant.

Gases kept at constant temperature if its temperature is change from 50 celsius to 100 celsius by what factor does the factor change?
The temperature factor increases to 1.1547, approx.
Do catalyst allow chemical reaction to take place at zero degree celsius?
Some catalysts can increase the rate of a chemical reaction at zero degrees Celsius, but not all catalysts are effective at such low temperatures. The effectiveness of a catalyst at low temperatures depends on the specific reaction and the nature of the catalyst.
The haber process is typically carried out at a temperature of 500 Celsius so what would happen if 100 Celsius?
If the Haber process were carried out at 100 degrees Celsius instead of 500 degrees Celsius, the reaction rate would be significantly slower. Lower temperatures would reduce the efficiency of the process, resulting in lower production rates of ammonia. It may also affect the equilibrium position of the reaction, favoring the reverse reaction.
Why do catalyst allow the chemical reaction take place at 0 Celsius?
When reactants are joined by a catalyst, they no longer have to collide with much energy to react. Thus, with the catalyst present the reaction can proceed at very low temperatures.
Is water have specific heat at constant volume or not?
Yes, water has a specific heat at constant volume, known as the specific heat at constant volume (Cv). This is the amount of heat required to raise the temperature of a unit mass of water by one degree Celsius at constant volume.
If HCL and Na2S2O3 are kept constant by how many degrees would this reaction have to be heated from 25 degrees C to precisely double the reaction rate?
Assuming the reaction is first order with respect to both HCl and Na2S2O3, increasing the temperature by 10 degrees Celsius will approximately double the reaction rate. So, you would need to heat the reaction from 25 degrees Celsius to 35 degrees Celsius to achieve this.
What temperatures are best for enzymatic reaction?

What is the value for the ionization constant Kw for water at 25 degrees celsius?
The ionization constant Kw for water at 25 degrees Celsius is 1.0 x 10^-14.
How long does the chemical take at 10 degrees celsius?
The duration for a chemical reaction at 10 degrees Celsius can vary depending on the specific chemical and reaction. Generally, a lower temperature like 10 degrees Celsius will slow down the reaction compared to higher temperatures. It is best to consult specific reaction kinetics or experimental data for a more accurate estimation.
Is f(x)-1 a constant function?
101.48 F = (101.48 - 32) x 5/9 Celsius = 69.48 x 5/9 Celsius = 7.72 x 5 Celsius = 38.60 Celsius
What is the unit for the calorimeter constant?
The unit for the calorimeter constant is typically Joules per degree Celsius (J/°C). It represents the amount of energy required to raise the temperature of the calorimeter by 1 degree Celsius.
Gases kept at constant temperature if its temperature is change from 50 celsius to 100 celsius by what factor does the factor change?
The temperature factor increases to 1.1547, approx.
Can water be made to boil at 90 degrees Celsius?
By decreasing the pressure with the volume kept constant.
