Question

The zero-order decomposition of ammonia on a hot tungsten surface proceeds according to 2 NH3(g) → N2(g) + 3 H2(g).

The reaction has a half-life of 2.40 × 10 seconds when the initial ammonia concentration is 2.00 M. How long does it take for the concentration of ammonia to decrease from 2.00 M to 1.16 M?
t=____ seconds

Question #: 7 The zero-order decomposition of ammonia on a hot tungsten surface proceeds according to 2 NH3(g) → N2(g) + 3 H2(g). The reaction has a half-life of 2.40 x 10 seconds when the initial ammonia concentration is 2.00 M. How long does it take for the concentration of ammonia to decrease from 2.oo M to 1.16 M? t= -seconds Report your answer with two significant figures. Do NOT include units in your answer. Use the format 2.2E2 or 2.2E-2 for numbers in scientific notation.
