Have to calculate activation energy ea in this question.
00:06
So, for that we can use our henius equation which is k is equal to e to the power minus ea by rt.
00:26
So, k is rate constant, ea is activation energy, k is equal to e to the power minus ea by rt.
00:36
So, now k is rate constant, a is exponential factor and r is gas constant, the value of r is 8 .314 joules per mole kelvin and the temperature is given at t1, the temperature is 298 kelvin, you have to convert the unit of the temperature in kelvin, it was given in the celsius, so 298 kelvin and t2 is 313 kelvin.
01:23
Now, we know the rate constant, the reaction rate doubles when temperature increases by 50 degree celsius.
01:31
So, rate constant is only affected by the change in temperature.
01:36
So, if the rate, reaction rate doubles, reaction rate doubles, so it means rate constant will also double, constant will also get double, it means k1 by k2 is equal to 1 by 2 or you can simply say that k2 is equal to 2k1, k2 is equal to 2k1.

Now, we have to put the values in this henius equation and solve this equation...
