1B ???
Assertion: The rate constant of a chemical reaction increases by a factor of 2 approximately on increasing the temperature by 10K.
Reason: The number of collisions increase between the molecules due to increase in temperature leading to increase in rate of reaction.
The choices are as per JEE options!!!!!!!!!
cheers!!!!!!!

4 statement 1 u should consult NCERT
ur 2nd statement is also a general fact but it doesnt lead us to statement 1
so CHEERS!!!!!!!!!!!!!
answer must be (B)
24Statement 1 is incomplete......(if we think it deeply....otherwise OK)
acc. to a research ....rate doubles only in small temp. ranges.......if temp becomes too large i.e greater than 400K.....then it is not valid....
21ya but eure dont think too much....
mera ans : B
BTW for wat statejent 2 wud v hav giv3en the ans as A coz this thing is lyk a general fact frm observation in variuos exp. [7]
24ok...tapan.....just wanted to give some knowledge
here ans is b(if dont think deep)
for ans to be a......maybe reason could have beeen the arhenius eqn....
1seems gud enough reason
baat to theek hi hai
and also explains the assertion
[7][7]
21Vish : i voted for B coz the reason gives no xplanatn for da fact that rate increases by "2".........
By the reason it cud inc by 10 also and 0.1 also..........
1yeah sahi baat hai sahi kaha tapan
ans is B
agar mathematical proof diya hota to A hota
[4][4]
