Multiple choice questions appear throughout both exam papers and at both Foundation tier and Higher tier. Multiple choice questions are usually asked as questions, often starting with 'what is You have four options to choose from in a multiple choice question.

6.1 Rate of Reaction

State two quantities that must be measured to establish the rate of a chemical reaction and cite several factors that affect the rate of a chemical reaction. The rate of a reaction is defined as the change in concentration as a function of time. Thus, the two quantities that must be measured are the molarity of either a reactant or product and the time. The factors that affect a reaction rate include the temperature, the concentration of reactants, the surface area if solids are involved in the reaction, and the presence or absence of a catalyst. This means that the rate of consumption of NO is twice as fast as the rate of production of N 2.

The rate of a chemical reaction is the change in concentration over the change in time. The rate of a chemical reaction is the change in concentration over the change in time and is a metric of the "speed" at which a chemical reactions occurs and can be defined in terms of two observables:. They both are linked via the balanced chemical reactions and can both be used to measure the reaction rate. This is an approximation of the reaction rate in the interval; it does not necessarily mean that the reaction has this specific rate throughout the time interval or even at any instant during that time. The instantaneous rate of reaction, on the other hand, depicts a more accurate value. The instantaneous rate of reaction is defined as the change in concentration of an infinitely small time interval, expressed as the limit or derivative expression above.

Все лампы наверху погасли. Не было видно даже кнопочных электронных панелей на дверях кабинетов. Когда ее глаза привыкли к темноте, Сьюзан разглядела, что единственным источником слабого света в шифровалке был открытый люк, из которого исходило заметное красноватое сияние ламп, находившихся в подсобном помещении далеко внизу. Она начала двигаться в направлении люка. В воздухе ощущался едва уловимый запах озона. Остановившись у края люка, Сьюзан посмотрела .

2.5.2: The Rate of a Chemical Reaction

 - У всех на виду. - Почему бы и. Испания отнюдь не криптографический центр мира. Никто даже не заподозрит, что эти буквы что-то означают. К тому же если пароль стандартный, из шестидесяти четырех знаков, то даже при свете дня никто их не прочтет, а если и прочтет, то не запомнит. - И Танкадо отдал это кольцо совершенно незнакомому человеку за мгновение до смерти? - с недоумением спросила Сьюзан.
