Question

For the first-order reaction t99%= x * t90%. The
value of 'x' will be :-
(1) 10 (2) 6 (3) 3 (4) 2​

Answer 1

Answer:

the value of X will be 10(a)

Answer 2

Concept Introduction: Chemical Kinetics is the basic part of all reactions in chemistry.

Given:

We have been Given:

$t_{99\%} = x \times t_{90\%}$

To Find:

We have to Find: The value of 'x' will be :-

(1) 10 (2) 6 (3) 3 (4) 2

Solution:

According to the problem,

$t_{90\%} = \frac{ln(10)}{k}$

and

$t_{99\%} = \frac{ 2ln(10) }{k}$

on comparing we get,

$x = 2$

Final Answer: The Value of

$x = 2$
