Sulphur in vapour state exhibits paramagnetic behaviour, why?
show that time required for first order reaction to go 99.9%completion is 10 times the half life period.
copper(I) ion is not stable in an aqueous solution.
For the reaction, BrO3+5Br-+6H+→3Br2+3H2O, . Find the value of
.
Rate of reaction can be expressed as:
-15d[Br-]dt=13dBr2dt
=(1.5×10-4) mol L-1 s-1.
HOW THIS 1/3 CAME ?
-dBr-dt=53×1.5×10-4molL-1s-1
= 2.5×10-4 mol L-1 s-1
PLZ ANSWER TO MY QUESTION .
a first order reaction is 15% complete in 20 min.how long will it take to b 60% complete????
a gaseous reaction, A2(g)-----B(g)+1/2C(g) shows increase in pressure from 100mm to 120mm in 5 minutes.The rate of disappearance of A2 is-
What are the difference between Order and Molecularity?
a first order reaction is 20% complete in 10 minutes. calculate the time required for the completion of 75% of the reaction.
what is the effect of using catalyst in a reaction on
(i) activation energy
(ii) gibbs energy of a reaction
1. Why do we get abnormal molecular masses from colligative properties? What is Vanât Hoff factor? How will you explain cases of association and dissociation of solute in such cases?
the rate constants of a reaction at 500K and 700K are 0.02s^-1 and 0.07s^-1 respectively. calculate the values of Ea and A
