The rate of disappearance of SO2 in the reaction 2SO2+O2→2SO3 is 1.28×10−3g/sec then the rate of formation of SO3 is
For a first-order reaction, the time required for 99.0% completion is twice for the time required for the completion of 90% of the reaction.
A reaction of first - order completed 90% in 90 minutes , hence , it is completed 50% in approximately :
An organic compound undergoes first-order decomposition. The time taken for its decomposition to 1/8 and 1/10 of its initial concentration are t1/8 and t1/10 respectively. The value of [t1/10][t1/8]×10 is ______ (take log102=0.3)
At 373 K, a gaseous reaction A→2B+C is found to be first order. Starting with pure A, the total pressure at the end of 10 min. was 176 mm and after a long time when A was completely dissociated, it was 270 mm. The pressure of A at the end of 10 minutes was:
