water, the freezing point was lowered by 6.36 degrees C. What is the
identity of this unknown compound?
Kef for water = 1.86 degrees C/m
(A) Cycle
(B) Kill
(C) Life
Answer- (D) Nalco
Which 0.1 moll aqueous solution will have the lowest freezing point?
Answer- (A) Al(NO3)3
(B) CaCl2
(C) C2H5OH
(D) Nalco
,What is the rate law of this reaction?
2H2 (g) + 2NO (g) --> N2 (g) + 2H2O (g)
(A) rate = k[H2] ^2 [NO]
Answer- (B) rate = k[H2] [NO]^2
(C) rate = k[H2] ^2 [NO]^2
(D) rate = k[N2] [H2O] ^2 / [H2] ^2 [NO]^2
The rate law for the reaction
A + B --> C + D
is first order in [A] and second order in [B]. If [A] is halved and [B] is
doubled, the rate of the reaction will
(A) remain the same
Answer- (B) be increased by a factor of 2
(C) be increased by a factor of 4
(D) be increased by a factor of 8
The half-life for the first order conversion of cyclobutene to ethylene,
, C4H8 (g) --> 2C2H4 (g)
is 22.7 s at a particular temperature. How many seconds are needed for
the partial pressure of cyclobutane to decrease from 100 mmHg to 10
mmHg?
(A) 0.101 s
(B) 52.0 s
Answer- (C) 75.5 s
(D) 5233 s
The half-life for the first-order radioactive decay of 32P is 14.3 days.
How many days would be required for a sample of a radio
pharmaceutical containing 32P to decrease to 20.0% of its initial
activity?
Answer- (A) 33.0 d
(B) 49.2 d
(C) 71.0 d
(D) 286 d
Plots are shown for the reaction N02 (g) --> NO (g) + 1/2 O2 (g)
